The Water Linked Underwater GPS (UGPS)

Underwater GPS G2 is Water Linked's latest Short BaseLine (SBL) system providing reliable accurate and robust acoustic positioning of a single Locator.
The G2 Topside is connected to the G2 Antenna which must be mounted in the water with direct line of sight to the Locator. A Wi-Fi signal emitted by the internal Web server of the G2 Topside allows the user to track the Locator using the Water Linked Web-based GUI. Users can also develop their own user interface using the Water Linked easy to use HTTP based API.
With the benefit of an integrated GPS and Inertial Measurement Unit (IMU), the GPS G2 provides absolute GPS position of the Locator, removing the need to integrate additional third-party sensors for accurate navigation. While only one Locator can be tracked the Locator can be set to one of 7 channels, allowing multiple GPS G2 systems to be used in the same area without interference.
Locators are available in one of 3 configurations to support the user’s requirements. The Locator must be synchronised with the Topside, which is achieved either through a GPS lock or through direct connection with the Topside, typically through the ROV tether
