ISRO marks 100th mission with successful launch of navigation satellite

What happened?

The Indian Space Research Organisation (ISRO) has successfully completed its 100th launch from the Sriharikota spaceport with the lift-off of a Geosynchronous Satellite Launch Vehicle (GSLV) carrying the NVS-02 satellite on January 29, 2025.

Why it matters to India:

The GSLV-F15 flight is the 17th mission of the Geosynchronous Satellite Launch Vehicle (GSLV) and the 11th successful mission using an indigenous cryogenic stage. This flight also marks the 8th operational flight of GSLV, featuring the indigenous cryogenic stage.
The NVS-02 satellite is a crucial addition to India’s Navigation with Indian Constellation (NavIC) system, a regional navigation satellite system designed to provide precise Position, Velocity, and Timing (PVT) services to users in India and regions up to 1,500 km beyond its borders. This launch updates India’s Regional Navigation Satellite System from four to five satellites, enhancing service reliability and performance.
