Testing an autonomous acoustic telemetry positioning system for fine-scale space use in marine animals

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 accuracy was about 2m. The choice of …
