Everything you need to know about Dead Reckoning for underwater navigation.

<h2>What is Dead Reckoning?</h2>

Dead Reckoning navigation, also known as "deduced reckoning," relies on the principle of estimating the current position based on the last known position, velocity, and heading. It involves using the direction and speed of movement to calculate where you are now relative to where you were previously. 

Dead Reckoning is particularly useful in scenarios where GPS signals are unreliable or unavailable, such as underwater environments where GPS signals cannot penetrate. This method has been integral to navigation, serving as a reliable means of orientation when other references are unavailable or unreliable.

“Dead reckoning is quickly becoming our new favorite way to operate underwater ROVs and understand positioning of our vehicles,” says Sam Macdonald, President, Deep Trekker. “Setting up USBL or flying completely blind is hard for us as users and our customers. We want to make the piloting experience as easy as possible.”

<img class="aligncenter size-large wp-image-7946" src="https://images.ctfassets.net/kzewhs8e6cvu/75aYvyERUL76xSHyy0TUl1/5bb1d9abeef5f17eb6bb50033d9039b2/Controller.png" alt="DESCRIPTION HERE" width="800" height="356" />

<h2>The Significance of Dead Reckoning in Underwater Navigation?</h2>

There are numerous challenges with underwater navigation. Unlike terrestrial or aerial navigation, where landmarks or satellites provide reference points, underwater environments offer minimal visual cues. 

Factors such as fluctuating ocean currents, variations in water density, and unpredictable underwater terrain further complicate the navigation challenges. Without reliable navigation, underwater vehicles run the risk of veering off course, potentially endangering both the vehicle itself and any onboard equipment or personnel.

Navigating underwater environments poses distinct challenges, requiring specialized techniques like Dead Reckoning to ensure safe and efficient operations. Underwater navigation lacks prominent landmarks or GPS signals, making reliance on Dead Reckoning a key method for underwater positioning.

This method, reminiscent of long-standing historical navigation practices, becomes particularly important in underwater operations where traditional navigation aids like landmarks or celestial bodies are inaccessible.

Understanding and implementing Dead Reckoning involves leveraging advanced sensors and algorithms to mitigate inherent challenges, such as sensor inaccuracies and cumulative drift. As technology progresses, optimizing Dead Reckoning capabilities becomes pivotal for enhancing underwater navigation.

<img class="aligncenter size-large wp-image-7946" src="https://images.ctfassets.net/kzewhs8e6cvu/3t6Sd0J8AmQJovMiFiUn2a/a62bd6232bd4c359e78a51496aabe8c7/Group_Glamor_Shot_crop1.jpg" alt="DESCRIPTION HERE" width="800" height="356" />

Deep Trekker’s PIVOT and REVOLUTION ROVs can operate with Dead Reckoning utilizing an upgraded inertial measurement unit (IMU) and Doppler Velocity Log (DVL) sensor combined with our BRIDGE software. The goal of these underwater ROV systems is to simplify the experience so customers can input an initial position and then get in the water and go. That doesn’t mean there aren’t any best practices you can leverage to optimize your experience!  Below are some tips and tricks to assist with your ROV piloting.

<h3> The 6 Rules of Dead Reckoning </h3>

The <a href="https://www.usna.edu/Sailing/_files/documents/2019_OSTS_Documents/Navigation_101_05MAR19.pdf">"6 Rules of Dead Reckoning"</a> are guidelines used in navigation, particularly in maritime and aviation contexts, to ensure that an estimated position (Dead Reckoning position) remains as accurate as possible throughout a journey. These rules help navigators keep track of their position and make necessary adjustments. To effectively maintain the vessel’s Dead Reckoning position, the navigator should follow theses 6 rules: 

__1. Regular Position Updates:__ Update the Dead Reckoning position at regular intervals, typically every hour on the hour. This helps account for changes in speed, course, and environmental conditions that may affect the estimated position. This periodic recalibration is essential for compensating for sensor drift, especially prevalent in underwater technology. Manual recalibration or resurfacing with GPS helps in correcting any deviations and maintaining accuracy.

__2. Adjustment after course changes:__ Following any alteration in the vehicle's course, promptly update the Dead Reckoning position to accommodate the modified trajectory. Utilize additional sensors such as a Doppler Velocity Log (DVL) sensor that tracks changes from the seafloor for underwater vehicles or Inertial Measurement Unit (IMU) sensors that track vehicle orientation changes to ensure alignment with the intended route.

__3. Adjustment after speed changes:__ Whenever there is a change in the vehicle's speed, it's also important to update the Dead Reckoning position immediately to help ensure that the calculated position remains accurate, considering the altered velocity.

__4. After every fix or running fix:__ A "fix" is a position obtained from external references, such as celestial observations, GPS, or terrestrial landmarks. A "running fix" is an ongoing series of fixes that helps refine the Dead Reckoning position. After obtaining either a fix or running fix, the navigator should update the Dead Reckoning position to incorporate this more accurate position information. In the case of an ROV, running fixes could be a GPS mounted on top that gets a fix whenever surfacing or a USBL getting pings during its dive. A fix also could be from a manual GPS input by the user when the ROV surfaces.

__5. After plotting a single line of position:__ A line of position is a navigational line that represents the possible positions of a vehicle at a specific time. It is determined using observations of celestial bodies, radar ranges, or other means. After plotting a single line of position, the navigator should update the Dead Reckoning position to account for this new piece of positional data.

__6. DR twice and label with Course and Speed:__ After every fix or running fix (repeated for emphasis). Reiterating the importance of updating the Dead Reckoning position after obtaining a fix or running fix. This ensures that the Dead Reckoning position continuously incorporates the most accurate position information available.

<h2>Integration of Dead Reckoning with Other Navigation Techniques</h2>

While Dead Reckoning serves as a foundational navigation method and can be a standalone tracking method, its effectiveness can be amplified through integration with complementary techniques. By combining Dead Reckoning with other navigation methods, such as acoustic positioning systems and satellite-based navigation, navigators can enhance positional accuracy and resilience to environmental challenges.

Acoustic positioning systems, such as Ultra-Short Baseline (USBL), Short Baseline (SBL), and Long Baseline (LBL), provide precise localization capabilities by measuring the time of flight of acoustic signals between transponders and the vehicle. By incorporating acoustic position updates into Dead Reckoning calculations, navigators can refine their estimated positions and mitigate drift accumulation.  

Similarly, satellite-based navigation systems, including GPS and GNSS (Global Navigation Satellite System), offer helpful external references for validating Dead Reckoning positions. While traditional GPS signals may be unavailable underwater, emerging technologies such as underwater GPS and Differential GNSS (DGNSS) enable precise positioning in submerged environments. By cross-referencing Dead Reckoning positions with satellite-derived fixes, navigators can ensure greater accuracy and reliability in their navigational estimates.

Furthermore, fusion algorithms, such as Deep Trekker’s Sensor Fusion algorithms, that integrate data from multiple sensors and navigation methods can optimize positional accuracy and robustness. By leveraging the strengths of each technique while compensating for their respective limitations, fusion algorithms provide a comprehensive solution for underwater navigation challenges.

<h2>The Role of Sensors in Dead Reckoning</h2>

Sensors play a significant role in Dead Reckoning by providing essential data inputs for calculating position estimates. Particularly in underwater navigation scenarios with ROVs, characterized by limited visual references, sensors serve as the eyes and ears of the vehicle, capturing crucial information about its movement and surroundings.

Various types of sensors are employed to track different aspects of the vehicle's motion. Doppler Velocity Log (DVL) sensors measure the vehicle's velocity relative to the seafloor by analyzing Doppler shifts in acoustic signals. This data is integral for calculating speed and direction changes, forming the basis of Dead Reckoning calculations. Additionally, Inertial Measurement Unit (IMU) sensors track the vehicle's orientation and angular velocity, providing necessary inputs for maintaining course accuracy.

Advancements in sensor technology, such as miniaturization and improved accuracy, have also enabled more sophisticated Dead Reckoning systems. MEMS (Micro-Electro-Mechanical Systems) sensors, characterized by their compact size and low power consumption, have become increasingly prevalent, offering a perfect blend of performance and efficiency for underwater navigation applications.

By leveraging the capabilities of these sensors, Dead Reckoning systems can navigate with improved precision, overcoming the challenges posed by the underwater environment and enabling safer and more efficient navigation.

<h2>Understanding the Limitations of Dead Reckoning</h2>

While Dead Reckoning serves as a valuable navigation technique, it is not without its challenges and limitations. Understanding these factors is important for mitigating risks and optimizing the performance of Dead Reckoning systems.

One notable challenge is the accumulation of errors over time, often referred to as "dead reckoning drift". This drift can arise from sensor inaccuracies, environmental disturbances, and uncertainties in the vehicle's dynamics. It’s important to note that these errors can compound, leading to considerable deviations from the true position, which is why periodic updates and recalibrations are so critical for maintaining accurate positional data.

<img class="aligncenter size-large wp-image-7946" src="https://images.ctfassets.net/kzewhs8e6cvu/3TrZ0cQz4kfCutps4JouW2/493cbc22b0518a8a03330a89d718df40/cirlce-of-uncertainty.png" alt="DESCRIPTION HERE" width="800" height="356" />

Dead Reckoning is also susceptible to disruptions caused by external factors such as ocean currents, water density variations, and submerged obstacles. These dynamic environmental conditions can impede the vehicle's trajectory, making it challenging to maintain accurate position estimates.

Additionally, reliance solely on Dead Reckoning in scenarios with limited external references, amplifies the risk of navigation errors. In such cases, a single miscalculation or sensor malfunction could lead to navigation errors with potentially serious consequences.

Addressing these challenges requires a multi-faceted approach, combining robust sensor technologies, advanced algorithms, and strategic operational practices. By continually refining Dead Reckoning systems and incorporating complementary navigation techniques, such as Deep Trekker’s Sensor Fusion algorithms, operators can navigate with greater confidence and reliability in challenging underwater environments.

<h2> Acquiring Photogrammetry Footage: From Planning to Precise Capture </h2>

Acquiring photogrammetry footage involves a structured process that varies depending on the specific application and available tools. To illustrate this process, let's explore underwater mapping as a specific example.

<h3> Planning for Precision </h3>

Before the cameras start rolling, meticulous planning is the cornerstone of a successful photogrammetry project. It begins by defining the target area or object, determining optimal camera positions and angles, and taking into account variables such as lighting conditions, water clarity, and turbidity. Effective planning sets the stage for accurate data capture.

<h3> The Art of Capturing Images </h3>

With a well-defined plan in place, the next step is to capture the images. In underwater mapping, this can be achieved through the use of remotely operated vehicles (ROVs) equipped with high-definition cameras or by deploying dive teams. The Deep Trekker ROV, for example, offers the convenience of the Mission Planner feature, enabling autonomous navigation along a predefined route while capturing images from multiple perspectives.

<h3> Navigating the Perfect Path </h3>

The chosen route for image capture can vary, from a spiral or wave pattern to straight paths, but the ultimate goal is to cover the largest possible area. 

![ROV possible route chart ](//images.ctfassets.net/kzewhs8e6cvu/6heYok4XXdh024X5FA82bq/12cedb177b504929fcce3683db08b682/Frame_10.png)

Achieving the best footage often requires a complete 360-degree rotation around the object. For precision, maintaining substantial overlap (50% or more) between successive photos is crucial. Close-up shots enhance texture detail, while shots from a distance aid in seamlessly stitching the object together.

![ ROV 360-degree rotation around a object](//images.ctfassets.net/kzewhs8e6cvu/65ENLhsci1zOYQlkxUz1G9/814803d88bb51016e1ede1e2ba81a776/Frame_11.png)

<h3> Mastering Image Quality </h3>

To ensure high-quality images, several factors come into play. Consistency in color balance is essential for accurate modeling. It's crucial to minimize movement of the ROV during image capture to prevent blurring and to avoid disturbing debris from the seabed. Utilizing fast shutter speeds minimizes motion blur, adjusting the aperture (high f-number) provides a broad depth of field, and lowering the ISO reduces noise in the images.

<h3> Processing the Captured Images </h3>

Once the images are in the can, the next step involves merging and processing them using specialized modeling software. This software employs algorithms to retain the details from each individual image, allowing it to create a point cloud—precise data about the size, area, and position of objects, like ship hull fragments. This point cloud serves as the foundation for mapping nodes or vertices onto a solid surface, ultimately forming the intricate mesh of the 3D model.


<h2> How Does Photogrammetry Software Work </h2>

Think of photogrammetry software as similar to putting together a 3D model. The computational task of photogrammetry is completed automatically in the background by the software, which analyzes the footage and identifies key features in each frame, including patterns or shapes. The first step, of course, is to ensure your image files are supported by the software you are using. From there, the process of turning images into a 3D model can be broken down into four primary steps:

<h3> Step 1: Aligning the Visual Pieces </h3>

The software's first task is to align the images in your dataset, precisely calculating their relative positions. This results in a set of images carefully coordinated to provide a clear and coherent perspective. It's during this step that the software begins to estimate depth information, assigning X, Y, and Z coordinates that will serve as the building blocks for the 3D model.

<h3> Step 2: Constructing a Dense Point Cloud </h3>

Once the images are aligned, the software creates a dense point cloud. This cloud is a virtual representation of the subject, populated with countless points, each holding both location and color information. These points collectively capture the intricate details of the subject, forming the foundation for a precise 3D model.

<h3> Forging the Mesh </h3>

Building on the point cloud, the software utilizes mesh generation techniques to connect the individual points together. Imagine this as a network of triangular polygons weaving the points into a coherent structure. This process is pivotal in shaping the subject's geometry within the 3D space.

<h3> Crafting Photorealistic Texture </h3>

Now bring the 3D model to life. The software draws upon color and texture data from the original images. It refines the model through texture mapping, infusing it with the hues and nuances of the real subject. This final step ensures that the 3D model not only captures the physical structure but also boasts a photorealistic appearance.

<h2> Finding Footage for Photogrammetry </h2>

<img class="aligncenter size-large wp-image-7946" src="https://images.ctfassets.net/kzewhs8e6cvu/5sM6RDNMt3mhw0FFcZ4pfK/55f0e7b543ed7c1e8d6b733f221c3aa0/gif-__LOOKING_UP_CLOSE_AT_SHIP_WITH_DEAD_RECKONING_TRACK_LINE_ON_SCREEN.gif" alt="DESCRIPTION HERE" width="800" height="356" />

Acquiring the right imagery for photogrammetry is a crucial aspect of creating accurate 3D models. The number of images needed depends on the subject's characteristics, including its size, shape, scale, and complexity. While intricate subjects demand hundreds of images captured from multiple angles, simpler objects may require only a handful.

Image resolution is a key determinant of photogrammetry quality. The resolution impacts the number of points that the photogrammetry algorithm can analyze, directly influencing the 3D model's precision and detail. 

<h3> Optimizing Image Requirements for Flawless 3D Modeling </h3>

Achieving flawless 3D modeling through photogrammetry requires a meticulous approach to image requirements. Several factors come into play, including image resolution, overlap, camera settings, lighting conditions, and image acquisition angles. One critical factor is the subject's physical characteristics. Photogrammetry software excels with textured, multi-colored, and organic subjects. In contrast, smooth, shiny, single-colored, transparent, or mirrored subjects pose challenges for proper image reconstruction.

<h3> The Crucial Role of High-Resolution Imagery </h3> 

Ultimately, the goal is to capture photographs (or video) in the highest quality possible, since it will directly impact the quality that the 3D model will be rendered in. Images with high pixel count ensure clarity and sharpness in the image capture, which will result in the creation of higher quality 3D models, so you’ll want to select video and image footage that is high resolution and clear to capture the finer details and ensure accuracy. 

<h3> Exploring Various Angles for Detailed Representation </h3>

When capturing images for photogrammetry to achieve a detailed representation, it's necessary to explore various angles and viewpoints of the object or scene. To achieve a detailed representation of an object, you’ll want to cover a wide range of perspectives. A detailed representation necessitates covering an array of perspectives, including but not limited to:

- __Top-Down View:__ This perspective offers a unique vantage point, capturing the subject from above, revealing its intricate details.
- __Front-Facing View:__ A straightforward view that presents the subject in its entirety, focusing on its frontal features.
- __360-Degree Rotation:__ Circling the subject from all angles ensures that no facet is left unexamined, yielding a comprehensive view.
- __Close-Up Shots:__ Zooming in to capture intricate nuances and fine details that may otherwise be missed.
- __Diagonal Views:__ Offering a dynamic angle, diagonal viewpoints can accentuate the subject's shape and characteristics.
- __Varying Heights:__ Experimenting with different heights allows you to capture your subject from various elevations, adding depth to the representation.

![ROV Various Angles for Detailed Representation](//images.ctfassets.net/kzewhs8e6cvu/1uPZYY7l4YjsaAenFcgFvK/0ffe81cb645da54df7945d8807119484/Frame_13.png)

Remember, it's not just about capturing these perspectives in isolation; it's equally important to ensure substantial image overlap (50% or more) between consecutive photos. This overlap is the linchpin of the final 3D model's quality, ensuring that no detail is left uncovered and that your model emerges with the utmost precision and accuracy.

<h3> How Does Proper Lighting Improve Quality of the Model </h3>

The quality of your photogrammetry model is significantly impacted by the lighting conditions during image acquisition. Adequate illumination of the subject is key to reducing the chances of distortion. Achieving the right lighting involves controlling external light sources, using diffusers or reflectors to soften and evenly distribute light, and avoiding extreme contrasts. Consistency in lighting throughout the entire shoot is paramount, making overcast days a preferred choice for outdoor shooting.

<h3> Factors to Consider When Choosing the Right Camera for Image Acquisition</h3>

When choosing the right camera for image acquisition in photogrammetry requires careful consideration of several key components to ensure the best results. Factors to weigh include:

- Image resolution
- Sensor size
- Lens quality
- Lens focal length
- Manual controls

Most importantly, you’ll want a camera with a high resolution sensor, and manual control over settings to capture the highest quality images. It is also essential to calibrate the camera to correct any lens distortion. 

Some other features to consider include stability, image format, and time-lapse and interval shooting. Many cameras now come with built in image stabilization, which will aid in capturing crisp, highly detailed images, and most digital cameras also support common file formats such as jpeg, which is supported by most photogrammetry software. Time-lapse capabilities also simplify the process and ensure consistent image capture.

<h3> Maximizing Precision in Reconstruction with Image Overlap </h3>

To achieve accurate and detailed 3D models in photogrammetry, image overlap is a critical factor in the process. It is essential to capture a significant number of images with overlap for precise reconstruction. The overlap is useful for matching features and establishing correlations to allow the photogrammetry software to stitch the images together and create an accurate 3D model. 

An overlap of anywhere from 50% up to 80% is generally recommended for best results of feature detection and matching, to improve the accuracy of the reconstruction. You’ll also want to keep in mind both side-to-side and back-to-front overlaps to help accurately align and triangulate features, and ensure optimal coverage of the subject from multiple angles. The more information you provide, the more accurate the reconstruction will be. 

Varying camera orientations and multiple passes are also incredibly useful for providing additional coverage and overlap, leading to more precise reconstructions. Additionally, you’ll want to minimize occlusions or obstructions which can prevent accurate feature matching and hinder the reconstruction process. If occlusions are unavoidable, capturing additional images from different viewpoints or angles can help compensate for the missing information.

<h2> How Much Should I Spend on an ROV? </h2> 

ROVs can cost anywhere from a few thousand to several million dollars. It can be confusing to determine what is right for you with such a broad range of options. Spending more typically means adding capabilities, but does not mean it is necessarily a better fit for the job. 

How much you should spend on an ROV is heavily dependent on the expected typical usage and core task functions. You can begin by evaluating the most integral functions for your project and choosing the most economical package to fit those requirements.

To create an ROV suited for industrial settings, different builds can accommodate add-ons like USBL, DVL, environmental sensors, and sonar. These features provide enhanced automation, tracking, vision, and depth features, but can come with a high cost ceiling and aren’t always required for the project at hand. Navigation packages utilizing DVL and USBL can cost $20,000 to $100,000 or more, depending on range and precision, while implementing sonars can range from $6,000 to $300,000. 

Simple inspections in still water may not need these high end features, and would better benefit from lower cost basic packages, designed for getting underwater visuals quickly and easily.

 <a href="https://www.deeptrekker.com/resources/underwater-rovs" target="_blank" rel="noopener">There are different categories of Remotely Operated Vehicles</a>:

Mini and micro class ROVs are swimming cameras that are great options for fast and effective eyes underwater. These can range from a few thousand dollars to $40,000 depending on the sophistication of the model and add-ons.

<h2> Considerations When Choosing an ROV? </h2>

ROVs are incredibly versatile tools, capable of a wide range of tasks. Because of this, there are a variety of features and add-ons that can be extremely beneficial for some industries, yet lackluster for others. The best ROV for the job is dependent on variables like the intended tasks, portability, average currents, water clarity, and depth requirements.

<h3>Intended Tasks</h3>

Evaluate what features are most important to your industry’s daily tasks. ROVs are capable of equipping add-ons such as environmental sensors, thickness gauges, positioning systems, sonar, cleaning tools, and more. Identify what is needed for your particular project, and then select the most cost effective, appropriate model and package to fit those needs.

<h3>Portability</h3>

Depending on the amount of travel or operational maneuvering, such as carrying an ROV to the top of a water tank, it’s important to consider the form factor of an ROV. Mini ROVs can fit into a single case for air travel as a checked bag, and are light enough to be carried while climbing a ladder. Larger observation or work class ROVs may come with additional features, but could be completely unusable for remote work environments.

![operator walking with case](//images.ctfassets.net/kzewhs8e6cvu/7Cgma5IryAvu83FjoZBE9m/8914a2bbb11ddb16f98ae1b18fbdf1c3/IMG_6095-Enhanced-NR.png)

<h3>ROV Control Through Current</h3>

Still water environments like water tank inspections will have little to no current, making it ideal for mini ROVs to conduct inspections. For offshore or high current situations, more advanced observation class models are required for enhanced control through stronger currents. 

A mini ROV like the DTG3 or PHOTON can handle currents up to 1-2 knots for general inspection tasks, providing reliable control in moderate conditions. For currents between 1-3 knots, the increased power of the PIVOT or REVOLUTION allows for effective maneuvering and stability.

However, it’s not just the size or power alone of the ROV that determines its ability to work in current. An ROV that utilizes sensor fusion will maximize its positioning capabilities through its intuitive software. Just like people, ROVs can work smarter, not harder.

<h3>Water Clarity</h3>

![Orange Force Marine murky water deployment](//images.ctfassets.net/kzewhs8e6cvu/2m5KGxHMKSVtdpdr09A1bg/d8530fed02b7f998c08f46016f6f7f65/JCD08937__1_.png)

Ideally, an <a href="https://www.deeptrekker.com/news/sonar-systems" target="_blank" rel="noopener">imaging sonar</a> would be on every ROV. It’s an incredibly helpful tool for most missions as it helps identify large objects from distances up to 120m (394 ft), and provides clarity on objects through murky water. The reality is that imaging sonars can cost upwards of $20,000 or more, making it a significant investment. To make sonar more accessible, Deep Trekker recently introduced the C550, a capable and affordable sonar priced at $10,000. Of course, not every project or application needs a sonar to be effective. In clear water, or if operations are in an enclosed area where it is easy to get visual references (such as under the hull of a ship or in a water storage tank), then you can likely conduct a successful mission without sonar.

Learn more about what sonar is and its many uses. Read about its applications, technologies, principles, and more.

<h3>Depth Rating</h3>

Working at depths? Always check the ROV depth rating before committing to a purchase. If the main goal of an ROV is to inspect or retrieve deep sea assets like seismic nodes, ensure that the depth rating is adequate for the mission. Deep Trekker offers models rated to depths of up to 305 meters, with standard tethers to 400 meters and special fiber optic tethers up to 2 kilometers long. Reach out to us with your specific project needs and we can help find the right tethers configuration. For extreme depths, large work-class ROVs are capable of reaching up to 11,000 meters. 

<h2> Choosing the Right ROV for Your Industry </h2>

![Family Photo Updated(photon)](//images.ctfassets.net/kzewhs8e6cvu/2MMzMN8XKm9yBNoJ8mJPiv/74119042d3beed3a37eee27c56d6ed8b/Family_Photo_no_bg.png)

<h3> Aquaculture </h3>

Typical usage within aquaculture includes net and mooring inspections and maintenance, mort pushing, and environmental sampling. Simple inspections can be completed with a basic mini ROV setup, but adding USBL positioning or Heading/Depth Sensors will help provide location information for points of interest. This creates a more robust inspection system and cuts down on dive times by offering exact positioning on breaches or other points of interest.

A grabber arm can also be implemented for object retrievals, or be used to utilize tools like <a href="https://www.deeptrekker.com/news/deep-trekker-and-uco-partner-to-advance-aquaculture-operations" target="_blank" rel="noopener">net patch kits</a>, mort diggers, or water quality sensors to build a dissolved oxygen profile. The DTG3 or PHOTON Package and PIVOT Smart are commonly used as a cost effective ROV solution for these tasks.

![UCO Boat aquaculture fish farm](//images.ctfassets.net/kzewhs8e6cvu/1KldjfsZs7D2uCtGOW7qUN/9edd887cbcdbfc0235304d5b628bf446/DJI_0351__1_.jpg)

<h3>Infrastructure (Civil Engineering)</h3>

For dam, intake, bridge, and piling inspections, it’s important to understand the typical operating water clarity. If the water is relatively calm and clear, a <a href="https://www.deeptrekker.com/news/difference-between-gvi-cvi" target="_blank" rel="noopener">general visual inspection</a> can be completed using a mini ROV such as the DTG3 or PHOTON. 

If these inspections require more significant structure detail, or are being conducted in challenging environments (High current / murky water), it may be beneficial to purchase a more powerful ROV with sonar functions. The DTG3 and PHOTON Package or PIVOT Expert with M3000 sonar are most commonly purchased for civil engineering applications.

![step 4 our process aerial infrastructure photo](//images.ctfassets.net/kzewhs8e6cvu/4kxHplC69dVOzRRXqF0Hn3/52d6a41c468f25235d5f7f7b0faffd83/infrastructure-rov-inspection.jpg)

<h3>Energy</h3>

For Nuclear Power, internal tank inspections are often in clear water. Due to the inherent potential hazards when working with nuclear energy, having a precise visual is integral. Implementing high quality zoom cameras and enhanced 4K cameras are the key to successful nuclear inspections. Deep Trekker’s REVOLUTION ROV equipped with a 4K camera and zoom lens is a popular system for these types of inspections.

For Hydroelectricity, inspecting intakes or sluice gates for proper function may just require a basic visual. Mini ROVs such as the DTG3 and PHOTON can accomplish the inspection and can be the preferential option for working in tight spaces. Some dams with higher flow and murkier water conditions would be better suited for the more powerful REVOLUTION or PIVOT equipped with sonar.  The DTG3 and PHOTON Package or PIVOT Expert with M3000 sonar are the most commonly purchased models for Hydro.

For Offshore Wind, inspections are essential to ensure the safety and functionality of turbine foundations, monopiles, and subsea cables. Regular checks of these critical components are necessary to prevent corrosion, structural damage, and marine growth that can impact performance. The PIVOT or REVOLUTION are commonly deployed to inspect the monopile base, scour protection, and cable entry points. With advanced stabilization, sonar, and 4K UHD cameras, these ROVs can navigate strong currents, providing detailed visuals of welds, bolts, and areas prone to biofouling - helping offshore operators maintain turbine integrity and extend asset lifespan.

<h3>Search & Recovery (SAR)</h3>

Target Search and Identification missions are far more effective with an imaging sonar. Having an ROV that can also tilt the sonar is a huge advantage, and Deep Trekker ROVs offer a distinct advantage by allowing operators to tilt the sonar, enabling them to adjust angles and optimize the field of view for any scenario. However if budget constraints are an issue, an ROV without a sonar is still a helpful tool for missions, as it still provides a method to quickly deploy eyes underwater. 

![Sonars for search and rescues ](//images.ctfassets.net/kzewhs8e6cvu/3D3Oljy2pjhhhtkj2pwiUE/35cd3ec4d227cf56bf9fc29a2d0dc25b/screen-Body_Location_Screen_Recoring__Uncut_-00-21-.jpg)

Beyond the search and verification of a drowning victim or evidence thrown overboard, ROVs can also assist with victim recovery. Using an ROVs grabber claw, the operator can latch onto and retrieve the target by pulling back on the tether. The ROV pilot also has the option to place a carabiner with a line onto the target. For more sensitive retrievals, teams can also have the ROV hold in place on the target, and deploy divers to follow the tether down for extraction.

The REVOLUTION or PIVOT Expert with M1200 are excellent ROV options for SAR missions. The M1200 sonar offers high quality imagery at ranges up to 30m (98ft). Experienced operators do not identify targets from further than 30m away from the target. This vindicates the limited range of the M1200 in comparison of the M750 and M370 sonars, since the tradeoff is enhanced clarity for superior identification. The interlocking jaws (<a href="https://www.deeptrekker.com/shop/products/interlocking-small-claw-attachment" target="_blank" rel="noopener">small</a> and <a href="https://www.deeptrekker.com/shop/products/interlocking-large-claw-attachment" target="_blank" rel="noopener">large</a>) are also useful add-ons for victim recoveries, as they are better suited for sensitive retrievals in comparison to the teeth of the grabber claw.

<h3>Commercial Diving</h3>

Vessel Inspections, Ship Husbandry, and Naval Damage Control are all common uses of ROVs in commercial diving. Whether it’s for emergencies, security, or maintenance, the first consideration during ship hull inspections is the strength of the opposing current. Mini ROVs may struggle in currents that observation ROVs such as the REVOLUTION and PIVOT can handle. Sonar can be a beneficial add-on for murky water conditions, or on larger ships to identify large defects or welded foreign objects.

</div>
<br>

ROVs are an effective method to add or enhance streams of business for a dive company, as some of their customers may prefer the ensured safety of ROV inspection. Having an ROV on hand provides more diverse service options to offer and market.

Many projects for commercial dive teams require pre-inspections, bid surveys to evaluate the project budget, or can benefit from having an extra set of eyes for dive monitoring. A simple mini ROV like the DTG3 or PHOTON can be a useful asset in this case.

ROVs can also be used to identify unexploded ordnance and mines underwater. Using an ROV that has an imaging sonar is key, similar to SAR. These missions can cover long distances, so utilizing USBL for position tracking and autopilot functionality is extremely helpful. The PIVOT NAV and REVOLUTION NAV with M750 imaging sonars are most popular in these cases, due to the long distance sonar capabilities and in-depth navigation features.

![20220128 101355](//images.ctfassets.net/kzewhs8e6cvu/5nbO5EZBbBb4rIGeS8wK97/2fccff8c3e706af61e49cd8e9b5b8124/revolution-rov-and-diver__1_.jpg)

Common packages differ depending on the desired scenario of the inspection:

- __For quick easy inspections__: DTG3, PHOTON Package or PIVOT Smart.
- __For thorough inspections__: REVOLUTION with M3000 Imaging Sonar, Cygnus Thickness Gauge, CP Probe.
- __Bonus tool__: MAG Crawler with M3000 Imaging Sonar is an excellent tool for hull inspections, since it is attached to the surface it is inspecting, it remains unaffected by strong currents, making it an ideal complement to an ROV.

Deep Trekker offers a comprehensive lineup of ROVs to suit all of the above industry tasks on nearly any budget. With predesigned packages plus customizable add-ons, it’s easy to build the perfect ROV to fit your specific needs.

<h2> What’s the Difference Between Deep Trekker ROVs? </h2>

Deep Trekker’s ROV lineup includes the DTG3, PHOTON, PIVOT, and REVOLUTION. 

![Deep Trekker ROV Family Deployment](//images.ctfassets.net/kzewhs8e6cvu/13QGsDr8cez2dWzbFBACUZ/72cd07d1332cffd6b501a2a8f4bc8f4e/Port_Security.gif)

The DTG3 is a mini observation-class underwater ROV built to deploy rapidly and quickly conduct visual inspections in underwater environments. Its lightweight design provides exceptional portability, but limits its power and feature capabilities, such as DVL sensor upgrades or an integrated tool platform. It operates using a three thruster design, meaning the operator will have to manipulate the pitch or yaw for vertical and lateral movements. The DTG3 is an excellent affordable option for simple underwater inspections.

The PIVOT and REVOLUTION are true observation class ROVs. Engineered with carbon fiber and stainless steel, the REVOLUTION delivers dramatic power, enhanced capabilities and inspiring performance in harsh conditions. The PIVOT offers a similar design to the REVOLUTION, but its scaled down size provides improved portability and maneuverability in tight spaces. Both models utilize six vectored thrusters to complete vertical and lateral movements, and come integrated with rotating tool platforms capable of carrying out a variety of tasks.

The PHOTON is a small-sized micro-ROV with the six thruster stability of the larger ROVs. The PHOTON is not the ideal platform for a large number of add-ons, and limits some of the features such as the ability to rotate the sonar or grabber like you can on the PIVOT or REVOLUTION, but still provides users with a capable experience in a smaller package and lower price.

The <a href="https://www.deeptrekker.com/products/underwater-rov/deep-trekker-revolution" target="_blank" rel="noopener">REVOLUTION ROV</a> is the most powerful, intelligent, and stable ROV in the Deep Trekker lineup. Its six vectored thrusters provide unmatched control in harsh underwater conditions, and when combined with its 305m depth rating, makes it ideal for complex deep ocean missions.

The integrated camera and grabber arm can rotate up to 260 degrees. This wide range of view means seamless transitions of focus points. The pilot can look up during a hull inspection, rotate to scan a wall, pan along the seafloor, or get the best angle to manipulate an object, all without changing the ROVs position.

A favorite feature of many operators is the rotating capability when adding an imaging sonar. With this ROV add-on, you can adjust the angle to sweep targets and get precise viewing angles. Because of its stable design and vertical thrusters which enable lateral movements, the REVOLUTION provides excellent performance with USBL and sonar.

You can also rely on extended battery operating time from a full charge. Thanks to the quick-change battery system, it's also extremely easy to perform field battery changes in well under a minute.

> "When everything was said and done, all three forebay inspections were completed 100% satisfactory, were done safer and faster, and with the innovation of using the REVOLUTION ROV vs. divers, has the ability to save my company millions for the investment of a few thousand into an ROV." - Thomas Griner, Operations Officer, Nuclear Power Facility, Midwest USA

<h3>Enhanced 4K UHD Camera</h3>

Capture finer details during inspections. The Enhanced 4K UHD Camera comes standard on PHOTON, PIVOT, and REVOLUTION ROVs, and is available as an upgrade for DTG3 models, offering superior clarity both at a distance and up close. 

Navigate to targets and capture high-quality images for your inspections and surveys with performance that significantly surpasses traditional off-the-shelf high-definition cameras. Featuring a turbidity filter, auto white balance, digital zoom, and automatic image enhancement, BRIDGE's advanced image processing algorithms ensure optimal underwater imaging. 

Discover how Deep Trekker’s enhanced 4K camera overcomes traditional challenges involved with underwater photography and inspections.

The 1080p camera included in the Base package of the DTG3 is a low-cost, off the shelf camera option used by many underwater drone and ROV manufacturers. It provides good quality imagery, but is limited in its focal range and effectiveness in turbid or dark environments.

The enhanced 4K camera delivers incredibly sharp videos to distinguish any fine details or irregularities during underwater inspections. The ultra wide lens on the 4K upgrade also allows for more content to fit on screen, and provides superior detail at shorter focal lengths. It also has a far greater range capability, allowing you to see detail further than with standard off the shelf 1080p cameras.
