Fri Jan 24 15:27:56 IST 2025: ## ISRO Prepares for 100th Launch: NavIC Constellation Expansion with NVS-02
**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 on January 29th. This milestone launch will deploy the NVS-02 satellite, the second in a series designed to enhance India’s indigenous navigation system, NavIC.
The GSLV-F15 rocket, featuring an indigenous cryogenic stage, will place NVS-02 into a Geosynchronous Transfer Orbit. NVS-02 is a key component of NavIC, providing accurate positioning, velocity, and timing (PVT) data across India and a 1,500 km radius beyond. The satellite offers both Standard Positioning Service (SPS) with accuracy within 20 meters and Restricted Service (RS).
Unlike its predecessor, NVS-01, launched in May 2023, NVS-02 incorporates L1, L5, and S band navigation payloads, along with a C-band ranging payload. Weighing 2,250 kg and with a power capacity of approximately 3 kW, NVS-02, built at the U. R. Satellite Centre (URSC), will replace the IRNSS-1E satellite at 111.75ºE. A notable feature is its use of a combination of indigenous and procured atomic clocks for superior timekeeping.
The launch marks a significant step in expanding NavIC’s capabilities and ensuring the continuity of its services. Five second-generation NavIC satellites (NVS-01 to NVS-05) are planned to bolster the constellation with advanced features.
