Abstract : Autonomous Underwater Vehicles (AUVs) require an accurate navigation system for operating in mine fields located in the near suff zone very shallow water. This research project examined the precision, performance characteristics, and reliability of a low cost, commercially produced, acoustical navigation system called 'DiveTracker'. The DiveTracker acoustical navigation system provides both an acoustical short baseline operator and the AUV with position data on a 1 hertz update rate. Experiments conducted on the DiveTracker system included static and dynamic tests which examined the system's ability to accurately measure distances and track a moving AUV under water.
