ISRO launches NVS-03 to revive NavIC after clock failures

UPDATE - follow-up to Why is ISRO’s NVS-03 satellite launch crucial? | Explained: GSLV-F18 successfully lifted off NVS-03 on 31 October 2026 at 23:51 IST from Satish Dhawan Space Centre, Sriharikota. The launch restores hope for India’s NavIC network, which has suffered from multiple onboard atomic‑clock failures and the inability to place the earlier replacement NVS‑02 in its planned orbit. The satellite will join the existing NavIC constellation to improve regional positioning services. ISRO confirmed the mission proceeded as planned and the payload is now on its intended geosynchronous orbit. The successful lift‑off follows a scheduled launch that had been set for 30 October 2026, also at 23:51 IST, after a brief postponement. NavIC, the indigenous navigation system, aims to provide accurate positioning across India and surrounding regions, and NVS‑03’s deployment is expected to compensate for the recent reliability gaps. ## Context The NavIC system complements global navigation satellites but relies on a stable set of satellites; any failure in clock or orbit placement reduces its accuracy, making each new launch critical.
