BSAT, Ejectable Black Box Recorder with Satellite Transmitter -has been developed by DRDO
BSAT, Ejectable Black Box Recorder with Satellite Transmitter -has been developed and tested by Naval Science and Technology Laboratory of DRDO in Visakhapatnam.
BSAT Ejectable Black Box Recorder device ejects from aircraft when it sinks after an accident and self-activates when it comes in contact with water, with a homing signal that can help rescuers easily locate the device.
BSAT Ejectable Black Box Recorder – Highlights
BSAT Ejectable Black Box Recorder Built as part of `Make in India’ initiative, the product, aimed for use on planes and submarines, has received “notice of allowance for patent” in the US and Russia.
BSAT Ejectable Black Box Recorder was developed based on the tracking technology currently used to detect torpedoes.
DRDO decided to develop it further and has perfected it for an aircraft. It aims to export the product after receiving approvals.
“In most of the air crashes in the sea, the conventional black boxes fail probably because they sink to the bottom of the ocean which could be thousands of metres deep and also get affected by the currents or damaged in the impact of the crash.
BSAT Ejectable Black Box Recorder is designed to overcome all these hassles. It will eject the moment an aircraft touches the water and floats on the surface. It can also be tethered to the flight so that some portion of the debris be retrieved.
The floating black box has a good use in defence as it can send out signals when a submarine goes below its prescribed depth and sinks, but its chief use would be in civil aviation.
The invention is good because it can the crash site and save flight information.
A black box stores data including speed, altitude and other parameters of the flight of an aircraft. The information is crucial to piece together the cause of an accident. Airbus and European aviation regulator are planning to have ejectable black boxes on commercial airliners in the next two years.
