Overview
- ISRO began a 24‑hour countdown and scheduled the GSLV‑F18/NVS‑03 lift‑off for Friday, October 30 at 11:51 pm IST from Satish Dhawan Space Centre.
- Engineers approved an unusual Mission Readiness Review configuration to fly NVS‑03 with its pyrotechnic valves open and added redundancy to bypass the connector failure that stopped NVS‑02’s orbit‑raising in January 2025.
- NVS‑03 carries an indigenous rubidium atomic clock alongside procured clocks and will add the L1 signal band in addition to L5 and S, widening NavIC’s compatibility with common smartphones and wearables.
- The flight will place the satellite into a geosynchronous transfer orbit and the mission’s success hinges on the spacecraft’s own liquid‑apogee engine completing post‑separation orbit‑raising manoeuvres to reach its final geostationary slot.
- If NVS‑03 becomes operational it will raise NavIC from three to four satellites capable of full positioning services, restoring reliability for train tracking, vehicle monitoring, maritime navigation and timing‑dependent infrastructure.
