Underwater Acoustic Positioning Systems Based on Buoys with Gps

  title={Underwater Acoustic Positioning Systems Based on Buoys with Gps},
  author={Alex Alcocer and Paulo Oliveira and A. M. Pascoal},
The paper addresses the general problem of estimating the position of an underwater target carrying an acoustic emitter by measuring the times of arrival (TOAs) of the acoustic signals at a set of surface buoys equipped with submerged hydrophones and GPS receivers. Examples of underwater targets of interest include AUVs (Autonomous Underwater Vehicles) and ROVs (Remotely Operated Vehicles) as well as manned submersibles, divers, and even marine animals. When compared with classical systems, the… CONTINUE READING
