'Make in India': This black box self-ejects, helps save vital data

Several aircraft have gone missing in mysterious circumstances — some never to be traced again, others found only after decades, like the remains of two airplanes that an amateur investigator found+ on Mont Blanc in the French Alps last week, which experts believe could be those of one of the aircraft that Air India lost in two crashes in 1950 and 1966.
But military R&D agency Defence Research Development Organisation (DRDO) has now developed a self-ejectable black box+ for airplanes. The 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. 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.
The product can prevent situations like the 2016 AN32 crash where in spite of using deep-sea probes, authorities were not able to trace debris in the sea.
BSAT — - Ejectable Black Box Recorder with Satellite Transmitter -has been developed and tested by Naval Science and Technology Laboratory of DRDO in Visakhapatnam. It attracted attention from experts at an exhibition "Science for Soldiers & Society" organised in Chennai at the CVRDE in Avadi.
Officials said the black box 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 receiveing approvals.
