Acoustic Command and Control Systems | HydroAcoustic Remote Controller (HARC)

Remote control of a wide range of underwater host packages is easily and effectively achieved with the L3 Oceania HydroAcoustic Remote Controller (HARC). HARC provides reliable remote control of multiple, uniquely addressed underwater devices in support of specific operational scenarios.

HARC consists of two main sub-systems — the surface deployed Transmitter system and the underwater Receiver system.

The Transmitter equipment is lightweight, portable and designed for ease of deployment and operation from small surface vessels such as a Rigid Inflatable Boat. This equipment consists of a Control Unit, a Battery Supply Unit and a hydroacoustic dunking projector. The intuitive operator interface consists of a single front panel with embedded membrane switches, alphanumeric display and status LED that can be customized to meet specific operator requirements.

The Receiver equipment consists of a DSP-based hydroacoustic modem provided on single low power PCB and a small hydrophone designed for installation in and integration with an underwater host package.

HARC has been extensively proven in the field with range reliability in excess of 10km, subject to environmental conditions.
