NVS-02 Satellite

Why in the news?                        

India's space agency, Indian Space Research Organisation (ISRO), has rolled out its Geosynchronous Satellite Launch Vehicle (GSLV) rocket, carrying the NVS-02 satellite, as part of the NavIC navigation system.

About NVS-02 Satellite:

• It is the second of the 5 second-generation satellites developed by the space agency to replace the existing satellites in the country’s navigation constellation Indian Regional Navigation Satellite System.
• It will be placed in a Geosynchronous Transfer Orbit by GSLV-F15.
  • NVS-01 was launched on board GSLV-F12 in 2023 and for the first time, an indigenous atomic clock was flown in NVS-01.
• It will replace an older NavIC satellite, IRNSS-1E, and be positioned at 111.75°E in orbit.
• It is designed, developed, and integrated at the U R Satellite Centre (URSC).
• Significance: By incorporating new L1 band signals, it improves NavIC’s compatibility with global navigation systems, ensuring wider adoption and better service.

Features of the Satellite :

• It is of 2,250 kg and has a power capacity of around 3 kW.
• It is configured with navigation payload in three frequency bands L1, L5 and S bands in addition to ranging payload in C-band like its predecessor-NVS-01
• It also has a precise atomic clock called the Rubidium Atomic Frequency Standard (RAFS) for accurate timekeeping.
• It has a longer lifespan of 12 years and also equipped with indigenously developed, more accurate atomic clocks.
