Key facts
| Parameter | Detail |
|---|---|
| Launch vehicle | GSLV-F18 (20th GSLV flight) |
| Satellite mass | About 2,250 kg |
| Initial orbit | Geosynchronous transfer orbit, 170 km x 37,023 km |
| Final orbit | Geostationary |
| Signals | New L1, plus existing L5 and S |
- NVS-03 is the third satellite of the Next Generation Navigation Satellite System, which continues the IRNSS series.
- It carries an indigenous atomic clock along with procured clocks.
- The launch should raise working NavIC satellites to the minimum needed to restore standalone positioning and timing services, as some older satellites have reached end of life.
- NVS-02 (January 2025) reached its initial orbit but could not climb to its final slot. A panel led by former ISRO chief A.S. Kiran Kumar found that an ignition signal failed to reach a pyro valve on the main engine’s oxidiser line.
About NavIC
NavIC (Navigation with Indian Constellation) is India’s own regional system giving position, velocity and timing services over India and about 1,500 km beyond. It offers a Standard Positioning Service and a Restricted Service. ISRO plans five second-generation satellites, NVS-01 to NVS-05. NVS-01 was launched on GSLV-F12 on 29 May 2023 and was the first to carry an indigenous atomic clock.
