About NavIC
  • To meet the positioning, navigation and timing requirements of the nation, ISRO has established a regional navigation satellite system called Navigation with Indian Constellation (NavIC).
  • NavIC was erstwhile known as Indian Regional Navigation Satellite System (IRNSS).
  • NavIC is designed with a constellation of 7 satellites and a network of ground stations operating 24 x 7.
  • Three satellites of the constellation are placed in geostationary orbit, at 32.5°E, 83°E and 129.5°E respectively, and four satellites are placed in inclined geosynchronous orbit with equatorial crossing of 55°E and 111.75°E respectively, with inclination of 29° (two satellites in each plane).
  • The ground network consists of control centre, precise timing facility, range and integrity monitoring stations, two-way ranging stations, etc.
  • NavIC offers two services: Standard Position Service (SPS) for civilian users and Restricted Service (RS) for strategic users.
  • These two services are provided in both L5 (1176.45 MHz) and S band (2498.028 MHz).
  • NavIC coverage area includes India and a region up to 1500 km beyond Indian boundary. NavIC signals are designed to provide user position accuracy better than 20m (2) and timing accuracy better than 50ns (2).
  • NavIC SPS signals are interoperable with the other global navigation satellite system (GNSS) signals namely GPS, Glonass, Galileo and BeiDou.
