India’s proud moment: ISRO’s GSLV-F18 puts navigation satellite NVS-03 into orbit
The 20th GSLV flight lifted off from Sriharikota at 11:51 pm on 30 October; NVS-03 strengthens NavIC, India’s own GPS-like navigation system.
India's space agency ISRO successfully launched the navigation satellite NVS-03 late on 30 October, adding a new satellite to NavIC, the country's own satellite navigation system.
The Geosynchronous Satellite Launch Vehicle GSLV-F18 lifted off at 11:51 pm IST from the Second Launch Pad at the Satish Dhawan Space Centre, Sriharikota. "GSLV-F18 has successfully placed NVS-03 in the intended orbit," ISRO said.
It was the 20th flight of the GSLV.
Why it matters
NavIC (Navigation with Indian Constellation) is India's independent regional navigation system, giving accurate position, navigation and timing services over India and a region extending about 1,500 km beyond it. It means India does not have to depend only on foreign systems such as GPS for critical navigation.
NVS-03 is the third satellite in ISRO's next-generation navigation series, built to keep the service running as older IRNSS satellites age. According to ISRO, it carries:
- an indigenous atomic clock, along with procured atomic clocks;
- a new L1 signal, in addition to the existing L5 and S-band signals.
Prime Minister Narendra Modi congratulated ISRO's scientists and engineers, saying the mission "marks an important step in strengthening NavIC" and that "the dedication and ingenuity of our space scientists continue to make our nation proud".
The rocket and the satellite
| Vehicle | GSLV-F18, three stages |
| Height | about 50 m |
| Lift-off mass | about 420 tonnes |

Watch the launch
ISRO streamed the launch live on its official YouTube channel.
What next
ISRO has begun orbit manoeuvres to raise NVS-03 from its transfer orbit towards its final orbit, its mission updates show. The satellite will then be tested before it joins the NavIC constellation.
