NavIC

1. Aadhar enrolment devices across the country is set to be integrated with NavIC.
2. Navigation with Indian Constellation (NavIC), a regional navigation satellite system was formerly known as Indian Regional Navigation Satellite System (IRNSS) is an Indian version of the American GPS.
3. It was established to meet the positioning, navigation and timing requirements of the nation based on the independent satellite navigation system.
4. designed with a constellation of 7 satellites, of which 3 are placed in the geostationary orbit and four are placed in inclined geosynchronous orbit.
5. It is connected to a network of ground stations operating 24 x 7.
6. The ground network consists of
   1. Control centre
   2. Precise timing facility
   3. Range and integrity monitoring stations
   4. Two-way ranging stations
7. Services offered by NavIC:
   1. Standard Position Service (SPS) for civilian users
   2. Restricted Service (RS) for strategic users
8. Coverage area of NavIC: Includes India and a region up to 1500 km beyond Indian boundary.
9. Provides a position accuracy better than 20m and timing accuracy better than 50ns to the user.
10. NavIC signals are interoperable with the other global navigation satellite system (GNSS) signals namely GPS, Glonass, Galileo and BeiDou.
