VADR Acoustic Directional Receiver for Subsea Vehicles  Small size and rugged design  Mounts easily on ROV or AUV  Compatible with ATT 400 series acoustic transponders to mark locations/equipment within 1 meter VADR SPECIFICATIONS  Access and Control Software provides operator with tracking formation for sound source The VADR (Vehicle Acoustic Directional Receiver) is Pinger Receiver Mode: Receive Bandwidth: 8 to 45kHz in 100Hz increments used to assist operators of ROVs and AUVs in tracking Receiver Sensitivity: -100dB ref 1µPa @ 1 meter acoustic sound sources from 8kHz to 45kHz. The VADR Transponder Mode: receiver can function as an “acoustic transponder inter- rogator” and provide accurate range and bearing to targets marked with a line of custom acoustic tran- sponders. It is operational to 6,000m (19,685ft) depth. Acoustic Signal: Coded The VADR receiver’s electronics and directional hydro- phone are contained in the pressure housing and are Directional Hydrophone: externally powered by a subsea vehicle through a 5-pin Beam Width: 40 ± 5 degrees Conical Bearing Indication: 4 BINS: Left/Right, 3, 8, 20 or > 20° Bearing Accuracy: 5 degrees nominal in BINS 1 and 2 Bearing Resolution: 2 degrees bulkhead connector. All telemetry data for controlling the VADR receiver, as well as output data, is accessed through the same connector. Control Interface: A RS232 data interface is used to access the directional RS232: 9600 Baud, No Parity, 8 Data Bits, and 1 Stop Bit indication, range to target, operational information and Connector: 5 pin Underwater Pluggable control functions of the VADR receiver using an ASCII Interface Software: Microsoft OS, Provided data string. Input Voltage: 18 to 32VDC, 24VDC nominal Mechanical/Environmental: Housing: Aluminum Hard Coat Anodized For tracking an acoustic sound source, like a “Black Box” beacon, the operator selects the proper frequency through the VADR software. The VADR receiver begins to look for that acoustic signal through a directional hydrophone which is mounted on the front of the pres- sure housing. Once received, the signal is processed by the electronics and fed to the software. Then bearing data and signal strength is provided to the ROV opera- Operating temp range: -18°C to 43°C (0°F to 110°F) tor for navigating the ROV to the target area.
