DiveNET: GPS is a portable, self-contained and rapidly deployable wireless wide-area underwater acoustic GPS navigation system based on a 4-buoy floating Long Base Line (LBL) array. DiveNET: GPS provides absolute, 3D coordinate underwater positioning inside the zone of coverage for an unlimited number of passive subsea Acoustic GPS Receivers (AGR).

DiveNET: GPS employs four hand-portable Acoustic GPS Buoys (AGB), deployed roughly around a dive site to set a long baseline for precise underwater positioning. AGBs can be positioned up to 700 meters apart for high accuracy positioning inside the coverage area - with low accuracy positioning extending for up to 2,000 meters around the site.


An unlimited number off passive Acoustic GPS Receivers (AGR) provide sub-meter positioning with GPS emulation output at a rate of 1 Hz. The AGR is designed to support OEM/third party integration solutions with common UART and NMEA protocol interfacing. 


The Diver Display Unit (DDU) is a personal DiveNET: GPS diver navigation device designed to support route planning, navigating, location marking and track exporting for analysis. The DDU supports up to 20 stored waypoints, 20 POI points, track export to KML/GPX, wireless charging and Bluetooth PC connectivity.

​DiveNET: GPS is designed for robust, straight forward operation in real world conditions, requiring minimal configuration and maintenance.


Maximum depth: 300 m (AGR) / 120 m (DDU).
