Underwater GPS Positioning System Based on a Dual Acoustic Device

Abstract:

In order to solve the problem that existing underwater GPS positioning technology can only realize positioning underwater target installing acoustic transponder, the underwater target positioning system having good dependability with ultra-short baseline (USBL), forward looking sonar (FLS) and GPS receiver was designed. Using the system to position presetting underwater target in the offshore area of Dalian, positioning accuracy reached 1.2m, according with theoretical derivation, and verifying the feasibility using the system to obtain the latitude and longitude of underwater target in WGS-84 coordinate system.
