India’s own regional navigation satellite system named as “Navigation with Indian Constellation (NavIC)” is established by ISRO and is functional from April 2018 onwards.
ISRO has completed all the necessary preparations with regard to establishment of Space Segment (currently Eight IRNSS satellites are in orbit) and Ground Segment (spread across India). The Seven satellites in the system are providing Positioning, Navigation and Timing (PNT) services and one satellite (IRNSS-1A) is providing messaging services.
The potential of this indigenous system is being demonstrated in various application sectors viz. vehicle tracking system, mobiles, timing & power synchronization, fisheries, surveying etc. For example, all commercial vehicles registered from 1st April 2019 onwards are mandated to have vehicle trackers, which are also NavIC-enabled. More than 30 companies are manufacturing Automotive Research Association of India (ARAI) or International Centre for Automotive Technology (ICAT) approved NavIC-enabled vehicle trackers in India. Through the provision of these services, the dependence on the American-owned GPS could be obviated.
