Underwater GPS G2 R100 Blueye Kit

Know where your ROV is located, and save it's position track onto a map. With Water Linked's purpose-developed positioning technology, unwanted noise no longer affects positioning accuracy the way it traditionally has with underwater positioning solutions. Get all images and videos geotagged automatically to ease reporting.

Water Linked
Waterlinked UGPS full kit

The UPGS G2 R100 Blueye kit consists of:

  • UGPS G2 Topside 100m range (inkl. Powerbank and USB-C charging cable)

  • Locator U1 (inkl. Blueye mounting bracket)

  • Antenna (inkl. 3x RAM mounts)

How does it work?

The G2 Topside is connected to the G2 Antenna which must be mounted near/in the water with direct line of sight to the Locator. The battery powered Locator U1 is mounted on to the Blueye ROV (No cable integration needed, therefor compatible with all Blueye ROV models). A Wi-Fi signal emitted by the internal Web server of the G2 Topside allows the user to track the Locator/ROV using the Water Linked Web-based GUI.

Technical Specifications

Underwater GPS G2 R100 Blueye Kit

The UGPS system is measuring the time it takes for a ping to travel from the U1 locator to the 4 transducers in the antenna. When the speed of sound in water is known we then get four sightly different distances. With classic triangulation the system can then provide a position estimate in X and Y, and the depth is measured with a pressure sensor.
