Fri Jan 24 09:57:56 UTC 2025: ## ISRO Prepares for 100th Launch: Next-Gen Navigation Satellite to Boost NavIC System
**Bengaluru, January 24, 2025** – The Indian Space Research Organisation (ISRO) is poised to launch its 100th mission from the Satish Dhawan Space Centre in Sriharikota at the end of January. This milestone launch will deploy the NVS-02 satellite, the second in a new generation of satellites designed to enhance India’s NavIC navigation system.
The GSLV-F15 launch vehicle, featuring an indigenous cryogenic stage, will place NVS-02 into a Geosynchronous Transfer Orbit. NVS-02, weighing 2,250 kg, boasts advanced capabilities including L1, L5, and S band navigation payloads, and a C-band ranging payload. Unlike its predecessor, NVS-01, it utilizes a combination of indigenous and imported atomic clocks for superior timekeeping.
NavIC, India’s regional navigation satellite system, provides accurate Position, Velocity, and Timing (PVT) services within India and an area extending 1,500 km beyond its borders. NVS-02 will replace the IRNSS-1E satellite at 111.75ºE longitude, improving the system’s overall precision and reliability. The five second-generation NavIC satellites (NVS-01 through 05) are designed to augment the existing constellation and ensure continuous service. The addition of L1 band signals will expand NavIC’s service capabilities.
Developed at the U. R. Satellite Centre (URSC), NVS-02 represents a significant advancement in India’s space technology, building on the success of NVS-01, which notably included an indigenous atomic clock. The upcoming launch marks a significant achievement for ISRO, underscoring India’s growing capabilities in space-based navigation.
