ISRO Launches NavIC NVS-03 Satellite on GSLV-F18 Mission
The Indian Space Research Organisation (ISRO) successfully launched the NVS-03 navigation satellite aboard the GSLV-F18 rocket from Sriharikota. This mission marks the 20th flight of the Geosynchronous Satellite Launch Vehicle and the third satellite in the second-generation NavIC series.
What happened
The Indian Space Research Organisation (ISRO) launched the NVS-03 satellite on the GSLV-F18 rocket from the Second Launch Pad at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The launch took place at 11:51 PM IST on Friday, October 30, 2026.
NVS-03 is the third satellite in the second-generation Navigation Satellite (NVS) series and the 12th satellite overall in the Indian Regional Navigation Satellite System (IRNSS) series. The vehicle successfully deployed the satellite into a Geosynchronous Transfer Orbit (GTO).
The spacecraft has a lift-off mass of approximately 2,250 kg and a planned mission operational life of 12 years. It is built on the I-2K satellite bus, developed by ISRO's U.R. Rao Satellite Centre and the Space Applications Centre. The satellite carries an indigenously developed Rubidium atomic clock and introduces civilian L1 band signals alongside the L5 and S bands for mobile and wearable interoperability.

- Memorize the payload details, including the lift-off mass and frequency bands.
PrepZen analysis
The successful launch of NVS-03 on the GSLV-F18 rocket represents a critical milestone for India's indigenous satellite navigation infrastructure. By restoring the active constellation to four operational satellites, NVS-03 meets the minimum quorum required for standalone GPS-style three-dimensional positioning.
Furthermore, the inclusion of the civilian L1 band alongside L5 and S bands enhances compatibility with mainstream consumer electronics like smartphones and smartwatches. Aspirants preparing for competitive examinations must focus on mission numbers, vehicle types, orbit classifications, and service coverage parameters.
