The Water Linked Underwater GPS Explorer Kit includes everything you need to get started with Water Linked modules for robust underwater positioning in your ROV, AUV, or other subsea system. The Master-D1 calculates the position of any Locator relative to the position of the Receivers with the APS100 technology. Combined with the integrated GPS and IMU, it will provide the absolute GPS position of the Locator. The operating principles can be found on the Water Linked website: Underwater GPS.

The Underwater GPS is similar to ultrashort baseline (USBL) systems often used on ROVs, but uses short baseline (SBL) technology that provides higher accuracy and better performance in complex environments such as water tank inspections, aquaculture, and infrastructure inspections.

With a small physical footprint, the kit is easily integrated into even the most compact equipment. It can be used retro-fitted to your system with the included cable, our integrated through your umbilical. 3D position data is accessed through an easy-to use API. Just power up and start exploring the underwater world!

For use with the BlueROV2, we strongly recommend getting the Water Linked Underwater GPS / BlueROV2 Integration Kit which makes it easy to seamlessly integrate the Underwater GPS into the BlueROV2 system.

The Water Linked product line also includes an acoustic modem for wireless underwater communication that resembles the positioning system’s Locators. These products can be used together simultaneously for wireless / untethered applications.
