A formation of unmanned vehicles for tracking of an acoustic fish-tag

In this paper we present a proof-of-concept for an hydro acoustic fish-tag position estimation and tracking system. In our field-tested concept, a formation of Unmanned Surface Vehicles (USV) creates a mobile array of low-cost hydro acoustic fish-tag receivers. The array of receivers is able to estimate fish-tag locations and follow the fish on open waters, significantly increasing capabilities as compared to moored systems. The paper describes the system architecture and components in detail. It also evaluates the proof-of-concept characteristics based on the experience gathered during the field-test.
