NavIC satellite placed into A Precise Orbit
The 17th flight of India’s Geosynchronous Satellite Launch Vehicle, GSLV-F15 successfully placed the NVS-02 satellite in the precise orbit as calculated earlier.
NVS-02, the second satellite in the NVS series is configured with Navigation payload in L1, L5 and S bands in addition to ranging payload in C-band like its predecessor-NVS-01.
It is configured on standard I-2K bus platform with a lift-off mass of 2250 kg and power handling capability of ~3 kW. It will be placed at 111.75ºE replacing IRNSS-1E.
NVS-02 uses a combination of indigenous and procured Atomic clocks for precise time estimation.
This was ISROs historic 100th successful launch. GSLV F15 rocket from the second launch pad at 06:23 hrs on January 29, 2025, carrying the NVS-02 navigation satellite.
Over a span of 99 launches, various missions have been carried out from Sriharikota. The GSLV-F15 with indigenous Cryogenic stage placed NVS-02 satellite into a precise Geosynchronous Transfer Orbit.
This was also the 11th flight with Indigenous Cryogenic stage. It was the 8th operational flight of GSLV with an indigenous Cryogenic engine launched from the India’s Spaceport Sriharikota.
GSLV-F15 payload fairing is a metallic version with a diameter of 3.4 meters.
Navigation with Indian Constellation (NavIC) is India’s own independent regional navigation satellite system designed to provide accurate Position, Velocity and Timing (PVT) service to users in India as well as the region extending about 1500 km beyond the Indian landmass, which is its primary service area.
NavIC is providing two types of services, namely, Standard Positioning Service (SPS) and Restricted Service (RS). NavIC SPS provides a position accuracy of better than 20 m (2σ) and timing accuracy better than 40 ns (2σ) over the primary service Area.
Five second-generation NavIC satellites viz., NVS-01/02/03/04/05 are envisaged to augment NavIC base layer constellation with enhanced features for ensuring continuity of services.
The NVS series of satellites incorporates L1 band signals additionally to widen the services.
NVS-01, the first of the second-generation satellites was launched onboard GSLV-F12 on May 29, 2023. For the first time, an indigenous atomic clock was flown in NVS-01.
Now for navigation within India and in the region extending 1500km from Indian boundary, we are no longer dependent on any other Countries navigation system.
