Context:
ISRO is set to launch its 100th mission, sending the 2,250-kg navigation satellite NVS-02 into space as part of a major upgrade to India’s navigation system.
- The satellite will be launched from the Satish Dhawan Space Centre in Sriharikota aboard the GSLV-F15 rocket, which features an indigenous cryogenic stage.
- It will launch the NVS-02 satellite into a Geosynchronous Transfer Orbit from the spaceport’s
second launch pad
About NVS-02:
- NVS-02 is the second satellite in the second generation of India’s Navigation with Indian Constellation (NavIC) system, which provides accurate Position, Velocity, and Timing (PVT) services across India and up to 1,500 km beyond.
- It is designed to enhance the NavIC system, ensuring the continuity of services with improved features. The NVS series (NVS-01, NVS-02, NVS-03, NVS-04, NVS-05) will replace older satellites and strengthen the system.
- NVS-02 was developed at the U R Satellite Centre (URSC), with support from other ISRO centers.
Key Features:
- Weighs 2,250 kg with a power capacity of around 3 kW.
- Equipped with navigation payloads in L1, L5, and S bands.
- Includes a C-band ranging payload, similar to NVS-01.
- Features a Rubidium Atomic Frequency Standard (RAFS) for precise time estimation.
- Designed for a 12-year lifespan and indigenously developed for better accuracy.
- Positioned at 111.75°E in orbit to replace the older IRNSS-1E satellite.
Service Enhancement:
- The addition of the NVS-02 satellite will expand NavIC’s services, with the first second-generation satellite, NVS-01, having been launched on May 29, 2023, aboard GSLV-F12.
| Note Geosynchronous Transfer Orbit It is also known as geostationary transfer orbit (GTO) and is a highly elliptical type of geocentric orbit, usually with a perigee as low as low Earth orbit (LEO) and an apogee as high as geostationary orbit (GEO). |
