In the next step, Geographic Information System (GIS) database is used to identify the probable crash site, Harinarayana explained.
The researchers report that their system locates a crash site "within a few seconds with good accuracy" making it more reliable and faster than the existing search-and-rescue method that relies on signals from special radio transmitters - or black boxes - carried on board airplanes.
According to Harinarayana, the new system has been successfully validated in four different cases of hypothetical plane crashes in Gujarat.
