Autonomous underwater vehicles (AUVs) used to locate multiple acoustic-tagged fish have previously been unable to alter their pre-programmed search paths to obtain precise position estimates. This problem is solved by the development of payload control software (Synthetic Aperture Override, SAOVR) that initiates maneuvers with trajectories favorable for estimating the tag's location from a synthetic...
We tested the capabilities and limitations of a novel autonomous acoustic positioning telemetry system with data from fifteen field deployments off the Florida coast. Telemetry array coverage areas ranged between 100 and 300m across. For fixed transmitters within the array, the fraction of transmissions leading to high-quality calculated position estimates averaged 44%, with wide variation. Positional...
