INDIA ORDERS DEEPWATER SYSTEM RECEIVER FOR “BLACK BOX” RECOVERY
National Institute of Ocean Technology(NIOT), in Chennai India, has awarded a contract to RJE International to supply a multifunctional acoustic directional receiver for their 6000m Remote Operated Vehicle (ROV). The AHS765 Acoustic Receiver will assist the ROV in locating and recovery of aircraft flight recorders or “black boxes” by homing in on the acoustic signal emitted by flight recorder’s acoustic beacon. With recent air disasters happening over deepwater, Directorate General for Civil Aviation and the Airports Authority of India has tasked NIOT to expand the capability of their ROV to assist aircraft disaster investigations.
To meet this challenge, RJE International and Falmouth Scientific Incorporated, of Catumet, MA has teamed up to deliver the subsea acoustic receiver designed not only to detected underwater acoustic beacons but transponders as well. The AHS765 is a versatile eight(8) channel receiver/interrogator that is operated from the surface using a RS232 interface with the vehicles control system. Custom software allows the ROV operator to determine range and bearing to the target beacon or transponder while providing full control of the receivers functions. The AHS765 small footprint makes it ideal for large and small submersible vehicles.
