GPS Based Underwater Positioning - A System Design

Ching-Tsann Leu, Jung-Jae Chao, and Tai-Shen Lee

Abstract:	A system design of GPS based underwater positioning is studied. GPS embeded buoys are employed as the reference points and broadcast messages for ranging and position fixing. The effects of waves of the sea, the large altitude variation in the GPS receiver and the underwater environment are considered. We uti- lize the filtering and the spread spectrum techniques to overcome the underwater data transmission and rang- ing problems. Computer simulation shows that the proposed system is feasible.
