Ever dreamed of swimming alongside coral reefs, exploring the beauty of shipwrecks, or the sea world – all from the comfort of dry land? Underwater drones, also known as Unmanned Underwater Vehicles (UUVs), are making this a reality. These innovative machines are shifting the way we experience the underwater world.

In this guide, we’ll dive deep into the world of underwater drones and uncover the top 7 drones in the market.

First, let’s take a look at the brief history of underwater drones.

History of Underwater Drones

Autonomous Underwater Vehicle (AUV) development began in the 1950s and has seen continuous advancements. Here’s a timeline of some key milestones:

1950s

The first AUV, classified as an unmanned underwater vehicle (UUV), emerged in the United States in 1957. The University of Washington designed the Special Purpose Underwater Research Vehicle (SPURV) to gather oceanographic data in Arctic waters.

1980s

The 1980s witnessed the merging of ROV (Remotely Operated Vehicle) technology with AUV capabilities. In 1983, ISE Ltd. and International Submarine Engineering collaborated to create the Autonomous and Remote Controlled Submarine (ARCS).

1990s

The 1990s marked a shift towards longer-term underwater exploration with the introduction of solar-powered AUVs. The credit goes to the Russian Institute of Marine Technology Problems, which introduced the Solar Autonomous Underwater Vehicle (SAUV) in 1987. Furthermore, the development of gliders in 1995 revolutionized AUV technology by allowing underwater submergence for weeks or even months at a time, thanks to extended battery life.

2000s

The 2000s saw a surge in AUV usage beyond mere testing tools. The growing international user base and increased funding for AUV development led to commercial sales. This shift expanded the scope of AUVs from research-based applications to industrial and commercial uses.

2010s and Beyond

In recent years, a renewed focus has been placed on the military applications of AUVs. Following the successful use of unmanned surface vehicles (USVs) by Ukraine in the Black Sea in 2022, the Ukrainian Navy adopted the Toloka TLK-150, a small robotic submarine, in early 2023.

In April 2024, Ukraine announced testing of an “unmanned submarine” capable of carrying divers, torpedoes, and missiles, and featuring extended range and endurance.

Types of Underwater Drones

Unmanned underwater vehicles (UUVs), also known as uncrewed underwater robots. They can navigate and operate underwater without requiring a human pilot on board.

These powerful vehicles come in two main categories: remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUVs).

1. Remotely Operated Underwater Vehicles

ROVs are connected to a control station or ship by a cable. This cable supplies power, allows for communication, and even transmits a live video feed to the operator. This tether allows for precise human control over the ROV’s movements and actions. situations requiring real-time decision-making, such as inspecting pipelines or conducting underwater search and rescue missions.

2. Autonomous Underwater Vehicles

AUVs are self-directed vehicles. They operate on their own, without a cable linking them to the surface. They are pre-programmed with specific mission instructions and rely on built-in sensors and computer systems to navigate, collect data, and complete tasks autonomously.

AUVs are valuable for gathering data over large areas or for venturing into deep or hazardous environments where human operation might be impractical or risky. They are increasingly being used for tasks like oceanographic mapping, environmental monitoring, and underwater exploration.

Key Components and Technology

A. Propulsion Systems

Underwater drones zip through the water using special engines. These engines, called thrusters, are like tiny propellers powered by electric motors. Thrusters can be positioned in different ways (think propellers on a boat vs. a jet ski) to push the drone in any direction, allowing for sharp turns and precise movements. Some underwater drones also have buoyancy engines, which act like underwater balloons. The drone can bob up and down by inflating or deflating these engines, controlling how deep it dives.

B. Navigation and Control Systems

Navigating and controlling an underwater drone is a complex task due to the challenges posed by the marine environment. Underwater drones employ a range of sensors to gather data about their surroundings and position, including:

• Inertial Navigation Systems (INS): Combining accelerometers and gyroscopes to track the drone’s movement and orientation.
• Depth Sensors: Measuring the drone’s depth using pressure or sonar-based sensors.
• Doppler Velocity Logs (DVLs): Using Doppler shift to measure the drone’s velocity relative to the seafloor or water.
• Acoustic Positioning Systems: Triangulating the drone’s position using acoustic signals from multiple reference points.

This sensor data is processed by onboard guidance systems, which use advanced algorithms and control systems to determine the drone’s position, plan its path, and issue commands to the propulsion systems.

C. Communication Systems

Radio waves don’t travel well underwater, so drones use special tools called acoustic modems. These modems are like underwater translators, turning information into sound waves that can travel far in the water. While acoustic modems are great for long-distance chats, they can be a bit slow.

For situations where a super strong connection is needed, some drones use tethered cables. Think of these cables as underwater lifelines – they provide a steady stream of power and crystal-clear communication, but they limit how far the drone can roam.

D. Payloads and Instruments

Underwater drones can be equipped with various payloads and instruments to perform specific tasks and gather data.

Common payloads include:

• Cameras: High-resolution cameras for visual inspection, mapping, and documentation.
• Sonar systems: For seafloor mapping, object detection, and underwater imaging.
• Sampling tools: Devices for collecting water, sediment, or biological samples.
• Manipulators: Robotic arms or grippers for interacting with and manipulating objects underwater.
• Scientific instruments: Sensors for measuring water properties (e.g., temperature, salinity, pH), as well as environmental monitoring equipment.

These payloads can be customized and integrated into the drone based on the specific mission requirements, enabling a wide range of applications in various domains.

Most DJI Avata 2 drones come bundled with a motion controller. It can be fun, but it’s not the best choice for those serious about their drone piloting skills.

Thus, the number one accessory you absolutely need is the DJI FPV Remote Controller 3.

It’s like your traditional remote controller, but with some extra oomph that’ll make your drone sing.

Why is it so great, you ask? Here are just a few of the ways:

• Lighter and longer battery time
• Tilt the camera to very specific positions
• Switch flight modes easier than the motion controller

These functionalities not only make flying smoother but also enhance your ability to capture the perfect shot, every time.

In three years, motion controllers might just be a fad, much like 3D TVs, whereas the tried-and-true remote controller will still be the go-to for precision flying.

Plus, there’s something satisfying about holding a proper controller in your hands. It makes you feel like a real pilot, not someone playing with a high-tech toy. And isn’t that what we’re all after?

2. Freewell ND Filter Set

Now, if we’re talking about making beautiful pictures, then you absolutely must get your hands on the Freewell ND filter set. The Freewell ND Filter Set is one of the best options available, offering ND 4, 8, 16, 32, and 64 filters.

But what exactly do ND filters do?

ND stands for Neutral Density. These filters are like sunglasses for your drone’s camera. They reduce the amount of light entering your camera lens without affecting the color. It allows you to slow down your shutter speed, even in bright conditions. This results in smoother, more cinematic footage that looks natural to the eye.

The Freewell ND filters are specifically designed to fit over the lens hood on the DJI Avata 2’s camera. While they might seem a bit tricky to install at first, once you get the hang of it, they’re a breeze to use.

Depending on your location and sky, you’ll likely find yourself sticking to an ND 8 or ND 16 filter.  Two of the most versatile filters.

For example, if you’re in a high UV index area like Colorado, where the skies are incredibly bright and the UV Index is typically 10, an ND 16 will be your best bet for capturing epic fly-through shots with deep blue skies and rich shadow details.

Pro Tip: If you’re flying indoors or in low-light conditions, you probably don’t need an ND filter. In fact, it might make your footage too dark. ND filters are primarily for outdoor use.

3. Extra Batteries

The DJI Avata 2’s flight time of approximately 18 minutes per battery charge can be limiting for extended shooting sessions. Investing in additional Intelligent Flight Batteries ensures you can maximize your time in the field without interruptions.  Keep in mind that it’s critical to use only OEM batteries.  We’ve seen too many issues with non OEM over the decade plus we’ve been flying drones.

4. Carry Case

You’ve just dropped a pretty penny on your Avata 2 and these awesome accessories. The last thing you want is to damage them while lugging them around. That’s where a good quality carry case comes in.

Look for something that’s sturdy, water-resistant, and has customizable foam inserts. This way, you can create the perfect snug fit for your Avata 2, controller, batteries, and filters.

A couple of the examples we like are the GPC cases, which are great but quite a bit more expensive than most, and the Lekufee Hard Case, which is a more affordable option for protecting your Avata 2 investment.

5. SD Cards and SD Card Holder

If you’re like us, you’ve found yourself in the position of not having enough SD card memory with you when you need it the most.  To keep this from happening, always ensure you have plenty of cards in your Avata 2 case.  As with most technology, there are tons of different types and sizes of SD cards to choose from.  One of our favorites is the SanDisk Extreme 256GB.  Solid performer with plenty of space and won’t break the bank.

When it comes to picking up an SD card holder, you’ll want to ensure it’s a hard case and that it is water proof.  Again, there are literally thousands to choose from.  We’ve absolutely loved using the PGYTECH CreateMate because it’s tough AND it doubles as a card reader.  Brilliant!

6. Maintenance and Care

To keep your DJI Avata 2 in top condition, don’t overlook these maintenance accessories:

• Cleaning Kit: Regular cleaning of lenses and sensors ensures optimal image quality.
• Prop Balancer: Balanced propellers contribute to smoother flights and reduced vibration in the footage.
• Spare Parts: Having extra propellers, screws, and other small components on hand can prevent unnecessary downtime.

Wrapping It Up

So there you have it – the best accessories for your DJI Avata 2.

Selecting the right accessories for your DJI Avata 2 can significantly enhance your drone piloting experience and the quality of your aerial photography and videography.

Start with the essentials – the DJI FPV Remote Controller 3 and the Freewell ND filter set. These two accessories alone will dramatically improve your flying experience and the quality of your shots. From there, you can gradually add other accessories as you need them.

Remember, while accessories can greatly improve your capabilities, they’re no substitute for practice and experience.

Eager to tap into his burgeoning field? This guide would be a great starting point.

In this guide, you’ll get a 360-degree understanding of Drone Inspection and how you can get started in this industry with a sense of clarity and ease.

Let’s get started.

What is Drone Inspection?

Drone inspection is the process of using unmanned aerial vehicles (a.k.a drones) equipped with cameras and sensors to inspect and evaluate structures, facilities, and infrastructure.

It provides a safe, cost-effective, and efficient alternative to traditional inspection methods. You can analyze the data collected from drone inspections to identify potential issues, track progress, and inform decision-making.

Before delving into the specifics of drone inspection, let us take a look at how drone inspection works.

How Does Drone Inspection Work?

The drone inspection can be broken down into three steps:

I. Preparing Drone Inspection Mission: Before any drone inspection, it’s important to properly understand and assess the terrain, local regulations, and required safety measures. You also need to identify the right drone for the mission.
II. Capturing Data: Drones collect data using payloads (e.g. camera sensors) suitable for the mission. This captured data is then sent for processing.
III. Analyzing and Interpreting Data: The final step is to analyze and process drone data using specialized software. This is where insights are garnered and communicated to the stakeholders.

Let’s check out what each step entails:

I. Preparing the Drone Inspection Mission

This involves FOUR simple steps:

1. Obtaining necessary permits and permissions: Check with the FAA (through one of the various flight approval app options) and local authorities to ensure you have the proper permits and permissions to conduct your inspection.
2. Conducting a site survey: Assess the inspection site for any potential hazards, obstacles, or challenging terrain.
3. Planning the flight path: Determine the most efficient and safe flight path for the inspection.
4. Conducting a pre-flight check: Ensure your drone is in good working order before taking off.

Now, picking the right drone is a crucial part of getting ready for a drone inspection mission. If you want to choose the perfect drone for your inspection work, here are some factors you should consider:

1. Range

The range of a drone is an essential factor to consider when purchasing one. If you need wider coverage and more varied shots during your inspection, a longer-range drone would be preferable.

Remember, though–the higher the flight range of a drone, the higher its price.

For example, the:

• DJI Air 2S has a range of 7.5 miles
• DJI Mavic 3 has a range of 9.3 miles
• DJI Mavic 2 Enterprise Advanced has a range of 6.2 miles
• DJI Matrice 30T has an operation range of 4.34 miles.

2. Camera

It’s also important to check the drone’s camera specifications, including shutter speed, frame rate, zoom options, aperture, and image stabilization. All of these factors can affect the quality of your photographs.

Pro Tip: You should settle for a high-resolution camera with a larger sensor and a 35mm equivalent focal length for your drone inspections. It will allow you to capture more detailed images of the object being inspected and improve image contrast, which helps generate accurate 3D models and point clouds.

3. Flight Time

A drone’s flight time is limited by its battery life. Cheaper models last only a few minutes, while more expensive ones typically have a flying time of around 25-40 minutes.

Here are the flight times of some popular drones:

• DJI Mavic Mini (up to 30 minutes)
• Autel Robotics EVO Lite+ (up to 40 minutes)
• DJI Mini 2 SE (up to 31 minutes)
• Autel Robotics EVO II (up to 40 minutes)
• DJI Matrice 30T (up to 41 minutes)

Pro Tip: Purchase additional batteries and charge them before leaving home to extend the flight time.

4. 3-Axis Gimbal

A three-axis gimbal is like a steadying hand for a drone’s camera. It helps to keep the camera steady while the drone moves around in different directions (such as up and down, tilting from side to side, and rotating.)

This is particularly important when using a drone for inspection, as the camera must remain level to capture accurate data and imagery.

Without a gimbal, the camera may shake or tilt, making it difficult–if not impossible–to capture the required data.

5. Payload Capacity

A drone’s payload capacity is the maximum weight it can carry in addition to its own weight. It’s vital to ensure that your drone has enough payload capacity to carry the necessary inspection equipment.

Having nailed the basic preparations of drone inspection, let us dive into the next section: Capturing Media.

II. Capturing High-Quality Data and Images

Since the data you collect from your inspection will form the basis of your analysis and reports, you need to ensure that you get the best possible visuals.

In this section, we’ll talk about how you can capture images that are clear, detailed, and useful.

A. Tips for Capturing Clear and Detailed Images

These tips will help you get high-quality visuals during your inspection.

1. Fly at the right altitude

First, it’s important to fly your drone at the right altitude. The optimal altitude for an inspection can vary depending on the size and nature of the area being inspected.

A good rule of thumb is to fly your drone low enough to capture the necessary detail, but high enough to avoid any obstacles.

For instance, while doing a roof inspection, you may need to fly closer to capture the details, but when inspecting a large property, you may need to fly higher to cover more ground.

Overall, try to experiment with different altitudes to find the sweet spot for your inspection.

2. Fly in good weather

Weather conditions can have a big impact on the quality of your images. To capture good images, it’s best to be aware of the weather conditions beforehand.

Avoid flying in adverse weather conditions such as rain, fog, or high winds, as they can affect the quality of your images and even put your drone at risk. So, for best results, choose a day with clear skies and good lighting.

You can also take advantage of real-time weather monitoring apps designed for drone pilots (such as UAV Forecast) to get detailed weather insights before and during your flight.

3. Use a gimbal

A gimbal is a helpful tool that keeps the camera steady and minimizes unwanted camera movement during flight.

This can make a big difference in the quality of your images, especially when flying in windy conditions.

Invest in a good-quality gimbal (ideally one that offers 3-axis stabilization) to ensure your camera stays steady and gets smooth shots.

4. Camera angle

Adjusting the camera angle is another important step in capturing images. Test out different camera angles to find the best perspective for your inspection.

In the case of a roof inspection, for example, you may need to tilt the camera to capture the correct angle, whereas a cell tower inspection may require you to rotate the camera to capture a 360-degree view.

Don’t be afraid to play around with different camera angles to get the best shot.

5. Grid lines

The grid lines on your camera screen can help you align your shots and capture images that are level and straight. This is especially useful when inspecting structures or objects that require precise leveling.

Use the grid lines to make sure your images are straight and level, and make any necessary adjustments before taking the shot.

B. How to Use Different Camera Settings to Optimize Your Images

Here are some must-know camera settings tips to help you optimize your images:

1. Adjust exposure settings for optimal image quality

Simply put, exposure determines how light or dark your images will appear.

You can use the histogram to analyze the exposure levels of your images and adjust accordingly to get a balanced image with details in the highlights and shadows.

2. Choose the right white balance for accurate colors

White balance balances the color temperature of your images to ensure that each color appears natural and true to life.

So, for a more accurate color representation, you can use the custom white balance function on your drone’s camera to match the environment’s lighting conditions.

3. Select the ideal shutter speed for clear images

Need a more cinematic look for your videos? You should preferably opt for a slower shutter speed.

However, if you’re looking to avoid blur caused by drone movement or wind in still images, you should use a faster shutter speed.

4. Use proper focus settings for sharp shots

Using the autofocus function is one of the best ways to keep your drone images sharp.

Better still, if you want to ensure that the focus is on the subject of interest, manual focus might be your best bet.

You can also try using focus stacking techniques for more detailed and clearer images.

Now, let’s discuss the third and most critical piece of the drone inspection process–Analyzing and Interpreting drone data.

III. Analyzing and Interpreting Drone Data

Capturing the media is half the battle won, as getting the right deliverables across to the client is what will make a real difference.

In this section, you’ll discover how to effectively do so without any hassles. We’ll cover:

A. Software that you can use for data processing and analysis
B. Analyzing drone inspection data
C. Creating reports from your drone inspection data

Let’s get started.

A. Software You Can Use for Data Processing and Analysis

Here are a few commonly used tools you can use to process and analyze drone inspection data:

• Pix4D: A comprehensive software suite that offers tools for photogrammetry, mapping, and data analysis.

B. Analyzing Drone Inspection Data

This is where the rubber meets the road. Analyzing drone inspection data is a crucial step in the inspection process as it helps to identify and highlight areas of concern that may require further investigation or action.

Here are a few important techniques you can use to do so:

• Image comparison: Image comparison is a technique where drone images from different flights are compared to identify changes or anomalies, such as cracks or structural damage.
• Point cloud analysis: This involves creating a 3D model of the inspection site to identify areas of concern, such as changes in terrain or surface irregularities.
• Data clustering: Data clustering is a technique where similar data points are grouped to identify patterns and anomalies, such as hotspots or areas of potential risk. Machine learning algorithms can also be used to automatically identify and highlight areas of concern, such as corrosion or leakage.

These techniques can help you effectively analyze and interpret your drone inspection data to ensure accurate inspections.

C. Creating Useful Reports from Your Data

Creating useful reports and visualizations is an essential part of the drone inspection process, as it helps you communicate the findings to stakeholders effectively.

Here are some techniques to create these reports and visualizations:

1. 2D and 3D mapping

Creating maps and 3D models of the inspection site is an effective way to visualize the data. It allows stakeholders to get a better understanding of the site and identify areas of concern quickly. This technique also helps create a baseline for future inspections.

2. Heat maps

Using color coding to highlight areas of concern is an effective way to draw attention to potential issues.

Heat maps can be created by analyzing data such as temperature, humidity, or moisture levels. It’s particularly useful for identifying patterns or trends over time.

3. Reports

Creating detailed reports that summarize findings and recommendations is essential to communicating the results of the drone inspection to stakeholders. Reports should be easy to understand and include visual aids such as charts and graphs.

What’s more, the reports should highlight the areas of concern and provide actionable recommendations to address them.

With a grasp of drone inspection technology, let’s explore its diverse uses in different sectors.

Drone Inspections Across Industries

Just as we mentioned in the introduction, drones are being used for inspections across different industries today.

Some of these industries include:

1. Mining

In the mining industry, drones can be very helpful in surveying vast and often inaccessible areas, including unstable stopes.

Pros and Cons of Using Drones for Inspections

While there are a lot of benefits to using drones for inspections, it has some limitations too.

Here’s a breakdown of some of the pros and cons of drone inspections:

Pros	Cons
1. Cost-effective: Since they typically require fewer personnel and resources, drone inspections are often less expensive than traditional inspection methods.  Companies can achieve significant cost savings by limiting scaffolding construction to times when maintenance work is actually needed.	1. Regulatory restrictions: There are strict regulations that govern where and how drones can be flown. For example, you can’t fly drones near airports, military bases, and other designated no-fly zones. While these laws are crucial for safety and privacy, they place limits on where companies perform aerial inspections.
2. Increased safety: Drones can access hard-to-reach, hazardous, or dangerous areas; this in turn lessens the risk of injury to personnel.	2. High initial cost: The upfront investment in drones and related equipment and software is very high.  Since the operation of these drones requires technical expertise, companies also need to invest in training for their personnel.  These costs can be prohibitive–especially for smaller businesses.
3. Time-efficient: Drones can quickly (and efficiently) inspect large areas or structures which reduces the time needed for inspections.	3. Limited range & battery life: Drones generally have limited flight range and battery life. This can be a challenge for companies that need more complex and large-scale inspections.
4. High-quality data: Drones are equipped with high-resolution cameras and sensors that capture detailed and accurate data. This allows for a more comprehensive analysis.  Thanks to the real-time data they provide, drones also enable inspectors to identify issues immediately and take swift action.	4. Weather dependence: Drones are very sensitive to extreme weather conditions–high winds, rain, or fog can severely impact their ability to fly safely and gather accurate data.  This dependence on good weather may cause unnecessary delays in inspections.
5. Reduced environmental impact: Drone inspections produce less negative environmental impacts compared to traditional inspection methods that often involve the use of heavy machinery, manned aircraft, or vehicles.	5. Accident-prone: Drones can easily crash due to factors like operator error or collisions with unexpected obstacles. And, given the high costs of these vehicles, a crash can result in significant financial losses.
6. Better decision-making: Drone technology can capture precise and comprehensive records of an asset’s condition throughout its life.  By archiving the visual data obtained, companies can create a digital record of the asset’s complete history, which can be accessed and analyzed at any given time. Besides facilitating more informed decision-making, this also enables businesses to improve their asset management strategies for better overall outcomes.	6. Detection limitations: Though drones are highly advanced, they may be unable to spot small or complex defects that a trained human inspector can easily spot.

 

Legal and Regulatory Considerations for Drone Inspections

While drones can be incredibly useful in inspections and increase safety, companies should ensure that their users operate drones legally.

Untrained drone pilots can crash, cause damage to the environment, and even harm workers. According to a study by UF/IFAS, between 2015 and 2020, approximately 4,250 people were injured by drones. The study also showed that 21% of those injured were under the age of 18, and 84% of the patients were male.

What’s more, according to the European Union Aviation Safety Agency (EASA)’s 2024 Annual Safety Review, there was one fatality and one case of a serious injury caused by a drone in 2023.

Hence, it’s important to consider legal and regulatory compliance before flying inspection missions.

First, energy inspections are typically conducted under API (American Petroleum Institute) rules.

In contrast, the American Society of Mechanical Engineers (ASME) creates codes for the development, fabrication, and assessment of boilers and pressure vessels.

There are several institutions, including API and ASME, that design standards and educational resources to carry out examinations in various sectors. In most countries around the world, their standards are usually regulated by law.

Moreover, to operate a drone legally while performing inspections through drones, pilots must follow Occupational Safety and Health Administration (OSHA) drone regulations as well as laws put forth by the Federal Aviation Administration (FAA).

The Federal Aviation Administration (FAA) regulates all civil aircraft operations in the United States, whether they’re manned or unmanned. Staying updated on developments from this agency is crucial for any drone inspection company. For example, it may be helpful to know that, since 2023, the FAA has been exploring ways to expand BVLOS (beyond visual line-of-sight) operations–which could benefit industries that require drones to cover long distances.

As of May 2024, the agency had approved a BVLOS flight for a drone for the first time.

Future of Drone Inspections and Emerging Technologies

The use of drones for inspections has become a valuable tool across various industries such as infrastructure, agriculture, and energy.

With the continuous advancements in technology, the future of drone inspections looks promising.

Here’s what we think in terms of the future outlook of drone inspection:

1. Artificial Intelligence (AI) and Machine Learning (ML)

As drones become more refined, we can expect them to use AI and ML to automatically analyze images and data collected during inspections.

This will enable faster and more accurate identification of defects and other issues, subsequently reducing the need for human intervention.

2. LiDAR

Light Detection and Ranging (LiDAR) technology uses lasers to create 3D maps of structures and environments. LiDAR-equipped drones can be used for high-precision inspections of infrastructure, such as bridges and wind turbines, as well as for mapping and surveying.

3. Augmented Reality (AR)

AR technology allows for the overlaying of digital information in the real world. This can be used in drone inspections to provide real-time data and visualizations. It can also assist inspectors in identifying potential issues and making more informed decisions.

4. Swarm Technology

A swarm of drones can work together to cover larger areas or complete complex tasks. This technology can be particularly useful for large-scale inspections or in hard-to-reach areas.

Drone swarm technology enables the collaboration of multiple UAVs (unmanned aerial vehicles) to execute diverse tasks that are either too complex or too inefficient for a single drone to perform alone.

5. Energy Harvesting

The ability of drones to harvest energy from the environment, such as solar power or wind power, will enable longer flight times and reduce the need for manual charging or battery replacement.

6. 5G Technology

Drones also stand to benefit from the improvements in connectivity brought about by the rollout of 5G networks. The adoption of this technology is likely to allow drones to transmit data more quickly and reliably.

Overall, the future of drone inspections looks promising, with the emergence of new technologies that will enable faster, more accurate inspections with greater automation and reduced human intervention.

Drone Inspection Market: Bigger Than We Can Think

According to a report by the American Society of Civil Engineers (ASCE), a significant number of America’s bridges are aging, with 42% of all bridges at least 50 years old and 7.5% structurally deficient.

What’s more, the infrastructure in the United States is extensive and requires maintenance. Currently, it has:

• over 600,000 bridges
• 4 million miles of public roadways
• approximately 140,000 miles of rail
• 600,000 miles of backbone transmission lines
• 5.5 million miles of residential power lines
• over 190,000 miles of oil pipelines and 2.4 million miles of gas pipelines

From these numbers, it’s obvious that infrastructure maintenance and inspection can’t be done by traditional methods using fifty-year-old snooper trucks or workers climbing on ropes

Therefore, drones are a natural choice for inspecting and maintaining the country’s vast infrastructure network.

The good news is that the Biden administration’s infrastructure proposal promises to invest a historic amount of money in building and reinvigorating the country’s infrastructure and human capital.

Plus, with the introduction of the Drone Infrastructure Inspection Grant Act (DIIG), more drones will likely be deployed to inspect and maintain critical infrastructure across the United States.

As a result, America is not only fixing its outdated infrastructure but also advancing and modernizing it.

In light of the proposed H.R.2864 bill, which could potentially ban DJI drones in the United States, a significant shift in drone regulations may be on the horizon. Although not yet passed into law, this Countering CCP Drones Act represents a pivotal moment in the evolving landscape of drone technology. It will impact how drones are integrated into our daily lives.

As we stand at the crossroads, we’d like to keep you informed and prepared for what lies ahead.

Let’s delve into the details and explore the future implications of the Countering CCP Drones Act.

Introduction to the Countering CCP Drones Act

Recently, the U.S. Congress voted on the Countering CCP Drones Act, a legislative move addressing national security concerns related to Chinese-made drones.

To reduce dependency on foreign technology and protect sensitive information, the act has further broadened the US-China technology conflict and brought it to light.

The act represents a federal initiative aimed at reducing the dominance of Chinese companies within the U.S. drone industry. Lawmakers have long expressed concerns that these drones, particularly DJI products, could be used by the Chinese Communist Party for surveillance purposes.

While the government has yet to provide definitive evidence supporting these claims, Chinese manufacturers have consistently denied the allegations.

This legislation seeks to curb the influence of Chinese companies, including DJI and Autel Robotics, by adding them to the Federal Communications Commission’s (FCC) Covered List. This designation identifies telecommunication equipment that may pose a risk to U.S. national security.

Notably, this action will not affect Chinese drones currently in use by hobbyists or private companies.

Historical Background and Development of the CCP Drones Act

The events unfolded on August 9, 2017, when a document from the Los Angeles office of the Immigration and Customs Enforcement Bureau was made public.

This document marked the end of extensive intelligence collection efforts involving specialists and external organizations.

The article was headlined, “Is DJI Possibly Sharing US Critical Infrastructure and Law Enforcement Information with the Chinese Government?” It explained that drones made by DJI in the United States, owned by unknown businesses and individuals, were sending data to DJI servers in China.

Soon, the U.S. Government and other agencies in the country began having apprehensions about the Chinese-manufactured drones as they could be altered for purposes of espionage. These concerns deepened further due to the strained relations between both countries regarding trade and technology.

In 2021, the Department of Treasury voiced concerns about the use of DJI drones in the surveillance of China’s Uyghur Muslim minority. The following year, the Department of Defense blacklisted the Chinese firm, making it hard for DJI to do business with the U.S. government.

In the same year, legislation seeking CCP drone regulations was introduced by Scott and Senators Tom Cotton (R-Ark.) and Marco Rubio (R-Fla.) in the Senate and by Representative Elise Stefanik (R-N.Y.) in the House, but it failed to move forward.

In 2023, Stefanik reintroduced the bill again in the House, paving the way for its inclusion in the House NDAA released in June. The same month, the legislation was also introduced in the Senate but it could not garner enough support to be included in the chamber’s version of the bill.

National Security Implications of the Act

The main focus of the Countering CCP Drones Act is to enhance the national security of the U.S. by safeguarding it against the usage of Chinese drones in the country. This act would help to reduce the risk and security threats posed by drones due to possible espionage, unauthorized data collection, and other possible threats.

Under this act, a review of the existing technologies is also made mandatory whilst the Department of Homeland Security is required to create strategies to manage and navigate the risks which are associated with such drones from foreign lands. Since this act restricts access to foreign drones, it would eventually help the U.S. government to mitigate and close possible vulnerabilities that may be caused to infrastructure and data systems.

Needless to say, a complete ban on the use of such drones would have far-reaching economic and technological implications. DJI is one of the top drone manufacturers extensively used in our country by commercial and hobbyist pilots. As per FAA records from August 2024, the total number of registered drones in the United States reached a substantial 785,827.

Currently, DJI drones are renowned for their unparalleled features and budget-friendly prices which make them a popular choice for leisurely flights and professional purposes. Hence, creating a ban on DJI would mean a disruption in the American drone market. There is a possibility of drone shortages resulting in spiked costs of drones for consumers and business owners.

On the other hand, the ban on Chinese drones could also encourage the growth of homegrown and alternative drone technologies in the United States. This could gradually lead to innovation and higher costs of drones in the long term.

US-China Technology Conflict: What to Expect Next

A potential Chinese drone ban means that the future looks bleak for the drone Industry. Even though the small players will gradually fill in the gap left by Chinese drone makers, the ban would lead to massive disruption.

However, it is pertinent to mention here that the government may allow a transition period of three years or more before the ban comes fully into effect. This transition would be time-consuming and expensive.

While traditional search and rescue (SAR) methods play a vital role in locating missing persons, they are inherently subject to certain limitations:

Geographic Constraints: Rugged terrain, dense forests, and large bodies of water can significantly impede the ability of ground search teams to effectively cover expansive areas. This limited reach can lead to delays in locating missing individuals.

Time Sensitivity: The success rate of SAR missions is highly dependent on rapid deployment and comprehensive search coverage. Traditional methods can be time-consuming to deploy and execute, especially in large-scale operations.

Safety Concerns: The challenging environments encountered during SAR missions can pose a risk to the safety of search teams themselves. This necessitates additional resources and protocols, further complicating rescue efforts.

While traditional SAR methods have served valiantly, advancements in drone technology provide a promising solution to overcome these limitations.

This option focuses more on the problem-solving aspect of drones and how they directly address the limitations you just outlined.

How are Drones Used for Search and Rescue?

Traditional search and rescue methods have served us well, but drone technology offers a game-changing advantage. Let’s see how drones tackle the limitations we just discussed:

1. Speed

Search and rescue missions (SAR) are all about speed. Drones can be launched quickly and cover huge areas in a fraction of the time it takes people on foot. This is critical because every minute counts in these situations – the faster someone is found, the better their chances of survival.

2. Safety

Drones also keep search teams safe. They can fly over dangerous areas like avalanches or floods, giving rescuers a clear picture of the situation without risking their own lives.

3. Eagle Eyes in the Skye

Drones equipped with high-resolution cameras are like the eagle eyes in the sky. The sharp, high-quality images and video footage of the search area allow search teams to identify potential clues or signs of the missing person, such as footprints, disturbed ground, or brightly colored clothing. A high-resolution camera can zoom in on potential campsites or trails, helping to pinpoint their location.

4. Thermal Imaging

Thermal cameras don’t rely on visible light but instead detect heat signatures. This is a game-changer for search and rescue at night, during foggy or smoky conditions, or even under thick forest canopy. Thermal imaging can reveal the body heat of a lost person, even if they’re hidden from view. This is especially valuable in situations where a person might be injured and unable to call for help.

5. Long Flight Times

Traditional methods may require search teams to return for breaks or refuel vehicles, delaying the search. drones can stay airborne for extended periods, allowing for thorough searches of vast areas. This is particularly beneficial in large-scale search operations or situations where the missing person’s location is unknown. With longer flight times, drones can cover more ground and keep searching for longer, increasing the chances of finding someone who may have wandered far.

We’ve explored how drones offer a technological leap forward in search and rescue. Now, let’s see these advantages in action with some real-world examples of drones saving lives.

The drone revolution has taken the world by storm, but with great flying power comes great responsibility, and sometimes, a few regulations. One of the latest additions to the drone pilot’s handbook is Remote ID.

As drones become increasingly embedded in our daily lives, from photography and delivery to agriculture and defense management, the need for the efficiency of the detection system has never been greater.

This guide will be your copilot, explaining what Remote ID is, why it matters, distinguishing features from Session ID, and how to ensure your drone is ready to take flight.

What is Remote ID?

Watch this video to learn how to legally bypass Remote ID requirements

Imagine a world where every car broadcasted its license plate information for everyone to see. That’s what Remote ID does for drones!

Remote ID refers to a system designed to provide identification and location information of drones in flight to other parties. It acts as a digital drone license plate, providing essential details like the drone’s ID, location, altitude, and operator information.

Drones with Remote ID capability transmit identification and location data via a broadcast signal, allowing reception by other parties.

In the next section, we’ll delve deeper into why Remote ID is important and how it contributes to a safer and more enjoyable drone flying experience for everyone.

Why Do We Need a Remote ID for Drones?

Remote ID establishes an essential safety and security framework required for advanced drone operations. It also assists the FAA, law enforcement, and other federal agencies in pinpointing the control station when a drone is observed flying in a hazardous manner or in restricted airspace.

The necessity for a Drone Remote ID arises from several key factors:

• Monitoring Air Traffic: Aids in monitoring and managing increasing drone traffic, reducing the risk of air collisions.
• Identifying Risks: Remote ID assists in identifying unauthorized or suspicious drone activities in sensitive areas.
• Promoting Accountability: By linking the drone’s ID to its registered owner, it encourages responsible drone use and adherence to regulations.

That being said, let’s dive into the background of Remote ID and how it came into existence. 

Remote ID Background

The concept of Remote ID for drones didn’t emerge overnight. It’s the culmination of years of discussions, technological advancements, and a growing need for safer and more organized airspace.

Regulatory bodies like the Federal Aviation Administration (FAA) in the United States have been at the forefront of developing standards for Drone Remote ID. These regulations are designed to integrate drones safely into the national airspace, laying the groundwork for advanced drone applications like beyond visual line of sight (BVLOS) operations.

The FAA’s Notice of Proposed Rulemaking (NPRM) regarding the Remote Identification of Unmanned Aircraft Systems was issued on December 31, 2019.

Over the 60-day comment period that followed, the FAA received more than 53,000 comments on the NPRM. The FAA thoroughly reviewed all these comments, and they were taken into account in developing the final rule.

The final rule, available in PDF format, was officially published in the Federal Register on January 15, 2021, initially set to become effective on March 16, 2021.

However, corrections to the rule were made and published in the Federal Register on March 10, 2021, leading to a delayed effective date of April 21, 2021.

There has been some confusion surrounding Remote ID and Session ID in the Drone community. So, we’d like to clarify that in the section below and help you understand the nuances of each.

How Session ID is Different from Remote ID

Let’s begin by clarifying what Session ID is.

While the Remote ID is a broad concept for drone identification, Session ID is a specific type of Remote ID.

In the future, those operating Standard Remote ID drones might have the option to broadcast either their drone’s ID (Remote ID-compliant serial number) or a Session ID.

The FAA is in the process of formulating a plan for assigning Session IDs to drone pilots, taking into account current policies during the development of the Session ID policy. 

The primary difference lies in the information shared and privacy considerations:

Remote ID	Session ID
It includes persistent identification of the drone and its operator. This means that the drone’s ID is always linked to its registered owner.	Session ID offers more privacy by linking a unique identifier to each session, without revealing the long-term identity of the operator to the public.

 

It is important to note that this Session ID still allows the drone to be tracked and identified during that session, but it doesn’t directly reveal the long-term identity of the operator to the public.

However, this capability won’t be accessible to the public. The FAA plans to gather public input on the Session ID policy before making it final.

The first step to becoming Remote ID ready is finding out if your drone is compliant or not.

How to Ensure Your Drone is Remote ID Compliant

With the importance of Remote ID established, let’s dive into the practical steps you can take to ensure your drone is compliant and ready for legal flight. Here’s what you need to know:

Step 1: Identify Your Drone

The first step is to determine if your drone is already Remote ID compliant. Many newer drone models, especially those weighing over 250 grams, come equipped with this technology.

Your drone’s user manual should explicitly mention if it has a built-in Remote ID or Broadcast ID.

Some manufacturers offer firmware updates that enable Remote ID on older drone models. Visit the manufacturer’s website and see if an update is available for your specific drone.

Step 2: Explore External Broadcast Modules

If your drone lacks a built-in Remote ID and cannot be updated, you might need an external Remote ID broadcast module. These handy devices attach to your drone and transmit the required identification and location data. Research compatible broadcast modules for your specific drone model and follow the installation instructions carefully.

Step 3: Register Your Drone

Drone registration is a separate requirement from Remote ID, but it’s still crucial.

Check out this link to learn the process of drone registration. This registration process links your drone’s unique ID with your personal information, ensuring traceability and accountability.

Step 4: Stay Informed

The world of drone regulations is constantly evolving. Stay informed by checking your local aviation authority’s website for any updates or changes to Remote ID regulations.

How to be Remote ID Ready

Drone pilots have three ways drone pilots can meet the identification requirements of the Remote ID rule:

1. Operate a Standard Remote ID Drone

Use a drone with built-in Remote ID broadcast capabilities that comply with the requirements of the Remote ID rule. It broadcasts identification and location information of the drone and control station. These Standard Remote ID drones come pre-equipped with the necessary features.

2. Operate a drone with a Remote ID broadcast module

The broadcast module can be added to a drone to retrofit it with Remote ID capabilities. A broadcast module is a device that broadcasts identification and location information about the drone and its take-off location in accordance with the Remote ID rule’s requirements. Pilots using a drone with a Remote ID broadcast module must maintain visual contact with their drone throughout the flight.

3. Operate without Remote ID equipment at FAA-recognized identification areas (FRIAs) 

In areas sponsored by community-based organizations (CBOs) or educational institutions that are recognized by the FAA, drone pilots can operate without Remote ID equipment. These FAA-recognized identification areas (FRIAs) are the only locations where unmanned aircraft systems (UAS), including drones and radio-controlled airplanes, may operate without broadcasting Remote ID message elements.

Final Thoughts

Wrapping it up, Drone Remote ID is kind of a big deal in our increasingly crowded skies. As the air traffic gets busier, keeping tabs on who’s who up there is a necessity for our safety.

But, here’s the kicker – privacy is hanging in the balance. Will it be a win for drone pilots? Well, that’s the million-dollar question, and honestly, nobody’s got the crystal ball on this one.

The system calculates the distance to each point, creating a dense point cloud of data using time-of-flight information.

Step 4: Process and Analyze Data

After collecting the data, you’ll need to process and analyze it. This typically involves combining the LiDAR point cloud with other data sources. Such as GPS and inertial measurement unit (IMU) data, to create accurate 3D models or maps of the surveyed area. You can then use specialized software to clean, filter, and classify the data, removing any noise or unwanted points.

Step 5: Visualize and Interpret Results

Once you’ve processed the data, you can visualize and interpret the results. LiDAR data can be displayed in various formats, such as 3D point clouds, digital terrain models (DTMs), or 3D meshes. You can use these visualizations to measure distances and volumes.

Additionally, you can detect changes over time, or make detailed maps and models for your project.

Step 6: Integrate and Share Data

Finally, you can integrate your LiDAR data with other geospatial technologies, such as Geographic Information Systems (GIS) or Building Information Modeling (BIM) software.

This integration lets you combine the LiDAR data with other sources.

These sources include aerial imagery and existing maps. You can use them to make complete and informative visuals. You can then share these visualizations and models to support decision-making and collaboration.

Remember, the specific steps may vary depending on the type of LiDAR system you’re using and the scale of your project. However, this general process gives you a good understanding of how LiDAR surveying works.

Let’s also consider LiDAR’s limitations for a well-rounded view.

Limitations of LiDAR Surveying

While LiDAR surveying offers numerous advantages, it also has some limitations that need to be considered:

1. Line of Sight Requirement

LiDAR systems need a direct line of sight to the target surface. Dense vegetation, buildings, or other obstacles can block that line of sight. This leads to pesky data gaps or occlusions in your survey results. This can be a real challenge in areas with many obstructions, like heavily forested or urban environments.

2. Weather and Environmental Conditions

Certain weather conditions, like rain, fog, or high winds, can put a damper on your LiDAR survey. These conditions can scatter or absorb those laser pulses, reducing the accuracy and completeness of your data. So, you need to keep an eye on the forecast before scheduling your survey.

3. Initial Cost

LiDAR systems and the necessary software and hardware can be quite expensive, particularly high-end models with advanced features. This upfront cost can be a hurdle for smaller projects or organizations with limited budgets.

4. Data Processing and Storage

Processing and storing a massive amount of data requires significant computing power and storage capacity. If your organization lacks the IT infrastructure or data management expertise, this can be a significant hurdle.

5. Skilled Personnel

Skilled personnel are the key to unlocking LiDAR’s full potential. They can identify the best uses for your project and ensure data collection and analysis yield the most valuable information. Without this expertise, you might be using a powerful tool at a fraction of its capacity.

With a solid foundation, let’s set our sights on the exciting future of LiDAR surveying.
