ISRO’s GAGAN to provide navigational support to Indian Railways

ISRO has announced to provide navigational support to Indian Railways through GPS Aided Geo Augmented Navigation (GAGAN) system.

The navigational support along with space technology-based tools will be provided to Indian Railways for unmanned level crossings safety.

By using GAGAN software system, a train will get to know the location of any unmanned level crossing by a warning signal. Once this warning signal is given, the train’s hooter will automatically start when it comes near an unmanned crossing.
