On 30 October 2026, ISRO launched GSLV-F18 from Sriharikota at 11:51 pm. The rocket placed the NVS-03 satellite in a Geosynchronous Transfer Orbit (GTO). Notably, it lifted off from the Second Launch Pad. Also, this was the 20th flight of the GSLV. Moreover, NVS-03 is the third satellite of the next-generation NavIC series. So, it ensures continuity of NavIC services.
What NVS-03 Carries
Specifically, the satellite carries an indigenous atomic clock along with procured atomic clocks. In addition, it adds an L1 signal to the existing L5 and S-band signals. Also, its coverage spans India and about 1,500 km beyond the borders. Further, PM Narendra Modi congratulated ISRO on the launch.
Orbit Raising Towards 111.75° East
Next, ISRO fired the satellite’s Liquid Apogee Motor at 4:48 pm on 31 October. The burn lasted 2,174.8 seconds. As a result, the orbit rose to about 5,477.6 km × 37,833.4 km. According to ISRO, the satellite health is normal. Further manoeuvres will take it to its geostationary slot at 111.75° East.
Why NavIC Needed NVS-03
Before this launch, only three NavIC satellites still provided services: IRNSS-1B, IRNSS-1I and NVS-01. However, standalone positioning needs at least four. Earlier, NVS-02 lifted off on GSLV-F15 on 29 January 2025. That flight was ISRO’s 100th launch from Sriharikota. Yet, a drive signal never reached the pyro valve of the oxidiser line. Hence, NVS-02 stayed stuck in an elliptical orbit. Therefore, NVS-03 will restore the minimum four-satellite constellation once it reaches its slot.
Other 2026 Navigation and Timing Milestones
Meanwhile, on 27 June 2026, an IndiGo A320 made India’s first GAGAN-guided commercial jet landing at Udaipur. Also, in July 2026, Union Minister Pralhad Joshi launched a White Rabbit-based IST dissemination network at RRSL, Bengaluru. Notably, it forms part of the “One Nation, One Time” initiative.

Why the NVS-03 Satellite Matters for UPSC and UKPSC
Notably, examiners like questions on NavIC signals, coverage and the NVS series. So, remember the L1 signal, the indigenous clock and the 111.75° East slot. Also, link NavIC with GAGAN, which ISRO and AAI built for aviation. For official updates, also visit ISRO. Next, for a related story, read about ISRO’s plan for four launch pads by 2029.
