The mission will place NVS-03, the third satellite in India’s second-generation Navigation with Indian Constellation (NavIC) series, into a Geosynchronous Transfer Orbit. The launch will mark the 20th flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV).

NVS-03 will further strengthen the NavIC constellation and help ISRO maintain uninterrupted navigation services. The satellite carries an indigenous atomic clock alongside procured atomic clocks.

It will also add the L1 navigation signal to the existing L5 and S signals, enhancing NavIC’s capabilities.

India developed NavIC as an independent regional navigation satellite system to provide accurate Position, Velocity and Timing (PVT) services across the country and an area extending around 1,500 km beyond its borders.

NavIC offers two services: the Standard Positioning Service (SPS) for civilian users and the Restricted Service (RS), an encrypted facility for authorised users.

ISRO also plans to deploy five second-generation navigation satellites to strengthen the existing constellation and maintain service continuity.

The agency launched NVS-01, the first satellite in the series, aboard the GSLV-F12 mission on May 29, 2023. The launch further marked the first flight of an indigenous atomic clock on an Indian navigation satellite.

The upgraded NavIC system will support transportation, location-based services and other applications that require reliable positioning, navigation and timing information.
