ISRO’s GAGAN to provide navigational support to Indian Railways [ Current News (Concise) ]
ISRO has announced to provide navigational support to Indian Railways through GAGAN (GPS Aided Geo Augmented Navigation) system. The GAGAN support along with space technology-based tools will be provided to Indian Railways for unmanned level crossings safety.
- A train will get to know the location of any unmanned level crossing by a warning signal through GAGAN software system. Once this warning signal is given, the train’s hooter will automatically start when it comes near an unmanned crossing.
- GPS Aided Geo Augmented Navigation (GAGAN) jointly developed by the ISRO and Airports Authority of India (AAI) for the advancement of air navigation.
- The GAGAN was launched in 2011 as a payload with GSAT-8. With this launch India had joined the club elite nations comprising of US, Europe and Japan who have the same level of space-based augmentation for navigational purpose.
- At present, GAGAN signal is broadcasted through two Geostationary Earth Orbit (GEO) satellites-GSAT8 and GSAT10. It is an indigenous navigational guide system developed on the lines of GPS system of the US.
