3D Sonar - Sonar 3D-15

Redefine your perception of the underwater environment. The Sonar 3D-15 is at the forefront of underwater exploration, delivering a clear, three-dimensional acoustic image that penetrates even the murkiest of waters.... More Info Less Info







Shallow water, often characterized by low visibility and high turbidity, typically renders optical cameras ineffective. While traditional 2D sonars offer some improvement, they fall short in providing a comprehensive understanding of the surrounding environment.

The 3D shaded view simplifies navigation, and the digitized point cloud data is ideal for detailed inspections and creating intricate models of both targets and the underwater terrain.

This enables autonomous systems to execute complex decision-making processes.

The Sonar 3D-15 sets itself apart with its compact and efficient design, boasting a 300 meter operational depth and a mere 0.5 kilogram in-water weight. Its small size makes it suitable for an extensive variety of ROVs, from the smallest to those of larger size, and empowering them with the ability to discern targets in challenging conditions.

Aligning with the Water Linked commitment for ease of use, the sonar’s Graphical User Interface (GUI) is designed for accessibility through a web-based browser. This user-centric design eliminates the complexity of software installation, simplifying the integration process.



Doppler Velocity Log - DVL A50

The A50 is the world’s smallest Doppler Velocity Log (DVL). By utilising the latest technology Water Linked has been able to reduce the size and cost of the DVL, while delivering a level of performance previously not
possible in a product so small.... More Info Less Info







Thanks to the size and weight of the DVL A50, the smallest ROVs and AUVs can now benefit from increased navigation and control. This allows these small vehicles operating in water depths down to 600m to perform tasks that would have previously required a larger and more expensive vehicle.

Although a clear benefit for small vehicles, larger vehicles requiring high accuracy navigation features also benefit from the size, weight, and cost benefits of fitting this high accuracy DVL.

While typically integrated fully to the ROV or AUV for enhanced control, the integrated Attitude and Heading Reference System (AHRS) within the A50 allows the DVL to be used for dead reckoning positioning. This feature allows the A50 to generate an accurate track plot of the vehicles movements without the need to fully integrate with the vehicle control system.



Doppler Velocity Log - DVL A125

The DVL A125 is the world’s smallest long range Doppler Velocity Log (DVL). By utilising the latest technology Water Linked has been able to reduce the size and cost of the DVL, while delivering performance previously not possible in a product so small.... More Info Less Info







Capable of maintaining bottom lock at speeds of up to 9 meters per second, and with an altitude range of 125m, the DVL A125 is the perfect DVL for ROVs, USVs and AUVs. The ability to also operate at an altitude as low as 5cm means the DVL will work at extremely short range as well as long range.

The size and weight of the A125 allows this DVL to be used on the smallest of vehicles, while having a depth rating of 3000m means this high performance DVL can also be used on vehicles that operate at these extreme depths.

Although a DVL is typically integrated fully to the vehicle for enhanced control, the integrated Attitude and Heading Reference System (AHRS) within the A125 allows the DVL to be used for dead reckoning positioning. This feature allows the A125 to generate an accurate track plot of the vehicles movements without the need to fully integrate with the vehicle control system.



USBL - UGPS Buoy & Locator (coming soon)

Access real-time georeferenced tracking of a diver or any underwater vehicle without the need for additional sensors or complex integration, with the latest Underwater GPS (UGPS).... More Info Less Info







This Ultra-Short BaseLine (USBL) system boasts a 300m range and can simultaneously monitor up to two targets fitted with UGPS Locators.

At the heart of the system, the UGPS Buoy wirelessly connects to your preferred device via an advanced web interface. With an integrated rechargeable battery, you’re assured of a full day of tracking on a single charge.

The buoy’s built-in GNSS receiver ensures precise location awareness, while its GNSS compass and integrated IMU allows for accurate georeferenced tracking of all the locators.

Select between two locator variants: the Locator B1, which is equipped with a built-in rechargeable battery, ideal for divers or short-term vehicle deployment, and the Locator C1, tailored for integration through direct power from its host vehicle.

Both locators are equipped with a GNSS receiver allowing accurate pre-dive positioning, as well as Bluetooth connectivity for seamless configuration via the buoy. In addition accurate depth data is provided thanks to an integrated depth sensor on each locator.

Enhance positioning accuracy further by integrating GNSS satellite corrections.

This advanced UGPS technology enhances underwater navigation by offering reliable real-time tracking of targets, complemented by a user-friendly

web interface for data display and logging.



Acoustic Modem - Modem M16

The Water Linked M16 modem is a miniature 16 bits per package underwater acoustic modem which has been designed for use in the most challenging of environments, where a reliable connection is of utmost importance.... More Info Less Info







Utilising the latest technology, developed for Aquaculture, Water Linked has produced a modem which provides a robust half duplex communication link with an acoustic range of 1,000m.

With a rapid boot-up time, the Modem M16 modem is ideal for use with subsea vehicles or instrumentation that has limited available power. When transmitting and receiving data, the M16 modem continues to offer the benefits of a low power solution requiring less than 2 watt seconds during transmission.

With 12 channels to choose from, operating around a 58.5 kHz centre frequency, multiple modems can be operated at the same time in the same area without interference.

Maintaining a small physical size and being lightweight was critical when designing the M16 modem for OEM integration, allowing the M16 modem to be integrated with little impact on the design of the overall system.

A transparent UART interface allows for simple low power connection to sensors, while an extended cable variation of the M16 modem is available with RS422 communication.
