The system may be repeatedly deployed in a slack surface buoy mooring in water depths ranging from 20 to 1,000 feet (6.1 to 304.8 meters).
The buoy system consists of a buoyant float assembly, an electronics package with VHF and UHF antennas, and omni-directional hydrophone with an electromechanical extension cable, and a rechargeable battery pack.
Underwater signals are received by the hydrophone and transmitted to the shipboard telemetry system via a VHF radio transmission where the data is transferred to a data handling system.
The buoy electronics are powered by a self-contained battery power supply.
Multiple single channel acoustic monitoring systems may be deployed simultaneously. A shipboard command transmitter may be used to control multiple systems via a UHF radio link as an alternative to the manual controls on the buoy system electronics package.
