Wireless Wide Area Subsea GPS Navigation

DiveNET: GPS is a portable, self-contained and rapidly deployable wireless wide-area underwater GPS navigation system. DiveNET: GPS uses four portable Autonomous Smart Buoys (ASB) to establish a floating long baseline (LBL) coverage area spanning up to 2,000 m in diameter. Sub-meter, absolute 3D coordinate positioning is provided for an unlimited number of divers or unmanned subsea targets inside the coverage area by a Subsea Navigation Unit (SNU) consisting of an acoustic receiver coupled with a position computer and depth/temperature sensor. DiveNET: GPS features an optional Diver Navigation Unit (DNU) personal GPS navigation indicator for route navigation, POI/Mark Point entry, and track export for post-dive analysis.
