The Indian Space Research Organisation (ISRO) is preparing for a landmark event with the 100th launch from the Satish Dhawan Space Centre in Sriharikota, scheduled for January 29. This launch features the GSLV-F15 NVS-02 mission.
Mission Details
- The GSLV-F15 rocket, equipped with an indigenous cryogenic stage, will launch the NVS-02 satellite.
- The satellite will be placed in a Geosynchronous Transfer Orbit from the spaceport’s second launch pad.
NavIC System
NVS-02 is part of the Navigation with Indian Constellation (NavIC), which is India's independent regional navigation satellite system designed to provide accurate Position, Velocity, and Timing (PVT) services.
- NavIC's primary service area extends about 1,500 km beyond the Indian landmass.
- It offers two types of services:
- Standard Positioning Service (SPS): Position accuracy better than 20 metres and timing accuracy better than 40 nanoseconds.
- Restricted Service (RS): Enhanced service for specific users.
NVS-02 Satellite
- NVS-02 is the second satellite in the NVS series, following NVS-01, launched on May 29, 2023.
- Configured with navigation payloads in L1, L5, and S bands, and ranging payload in C-band.
- Uses a combination of indigenous and procured atomic clocks for precise time estimation.
- Designed on the I-2K bus platform with a lift-off mass of 2,250 kg and power handling capability of ~3 kW.
- Will replace IRNSS-1E at 111.75ºE.
Development and Integration
- The satellite was designed, developed, and integrated at the U. R. Satellite Centre (URSC) in collaboration with other satellite work centres.
