Abstract
Underwater wireless localization systems are expensive due to the cost of hydrophones. The method and the architecture of the localization system should be adapted to the environment constraints. This work deals with the trade-off between the affordability and the accuracy of underwater localization. We prototyped our low-cost hydrophone-based beacon location system. Simulation results show that our location precision error is under 1.5 meters in a constrained area at very low cost.
