ISRO Navigation Satellite

With India's navigation satellite system - Navigation with Indian Constellation (NavIC) - not fully functional, one of the biggest concerns is that the country will be unable to use it for security and strategic purposes, experts say. The major setback occurred after the last atomic clock on board the Indian Regional Navigational Satellite System-1F (IRNSS-1F) stopped functioning on March 10, leaving only three satellites of the constellation capable of providing position, navigation, and timing (PNT) services. At least four satellites with operational atomic clocks are required for the navigation satellite system to function properly. Ananya Ray, a former scientist with the Indian Space Research Organisation (ISRO), told PTI in an interview, "Systems like NavIC have two signals: an open signal for common people and a restricted military signal that increases accuracy roughly tenfold." Armed forces of countries use the navigation satellite system for logistics, mapping and operatio

India's indigenous satellite navigation system NavIC faces fresh reliability concerns after IRNSS-1F's atomic clock failure, raising questions about the resilience of the country's navigation constell

The 27-hour countdown for ISRO's historic 100th mission from this spaceport, launch of a Navigation satellite onboard a GSLV rocket commenced on Tuesday, sources in the space agency said. Also, this would be the first mission for ISRO Chairman V Narayanan, who assumed office on January 13. The Geosynchronous Satellite Launch Vehicle (GSLV) with indigenous Cryogenic upper stage in its 17th flight, carrying the navigation satellite NVS-02 is scheduled for lift-off at 6.23 am on January 29 from the second launch pad here. The navigation satellite is the second in the series of the Navigation with Indian Constellation (NavIC) aimed to provide accurate position, velocity and timing to users in the Indian sub-continent as well as to regions about 1,500 km beyond the Indian land mass. "The 27.30 hour countdown commenced at 02.53 am on Tuesday," multiple sources told PTI. The 50.9 metre tall GSLV-F15 follows the GSLV-F12 mission which successfully carried navigation satellite NVS-01, the .
