NVS-02 Satellite: Boosting India’s Navigation System Capability

Launch and Purpose:

  • Satellite: NVS-02, launched by ISRO, is the second satellite in India’s second-generation NavIC system.
  • Launch Vehicle: The satellite was launched aboard the Geosynchronous Satellite Launch Vehicle (GSLV-F15).
  • Objective: NVS-02 aims to enhance India’s regional navigation capabilities through the NavIC (Navigation with Indian Constellation) system.

Key Features of NVS-02:

  • Weight: 2,250 kg, equipped with advanced navigation technologies.
  • Rubidium Atomic Frequency Standard (RAFS): Provides precise timekeeping for navigation data.
  • Payloads: Includes navigation payloads operating on L1, L5, and S frequency bands, along with a C-band ranging payload for accurate positioning.
  • Geosynchronous Positioning: Positioned at 75°E in geosynchronous transfer orbit, ensuring accurate data transmission.
  • Lifespan: The satellite has a 12-year operational lifespan.

Impact and Applications

  • Replacing Aging Satellite: NVS-02 replaces IRNSS-1E, improving the NavIC system’s performance and longevity.
  • Global Compatibility: With the inclusion of L1 band signals, it improves compatibility with global navigation systems, promoting wider adoption.
  • Applications: The satellite will benefit multiple sectors, including navigation, precision agriculture, fleet management, emergency services, and mobile device tracking.
  • Significance: NVS-02 strengthens India’s self-reliance in space technology, advancing the country’s capabilities in global navigation.
