News: The Indian Space Research Organisation (ISRO) has reported a technical glitch in its NVS-02 navigation satellite, launched on January 29, 2025, as part of its 100th successful mission.
About NVS-02
- NVS-02 is an advanced navigation satellite launched by the Indian Space Research Organisation (ISRO) as part of India’s Navigation with Indian Constellation (NavIC) system.
- It is designed to enhance India’s independent regional navigation capabilities and provide accurate positioning services.
- Launch Vehicle: GSLV-F15 (Geosynchronous Satellite Launch Vehicle)
- Orbit Type: Geostationary Transfer Orbit (GTO), intended for final positioning in a geostationary orbit
Purpose and Objectives
- NVS-02 is part of ISRO’s efforts to build a self-reliant satellite navigation system for India, reducing dependence on global systems like GPS.
- It aims to enhance Position, Velocity, and Timing (PVT) services for civilian and military applications.
- It supports users in India and regions up to 1,500 km beyond the Indian landmass.
- The satellite plays a crucial role in sectors such as transportation, disaster management, precision agriculture, and scientific research.
Technical Specifications
- NVS-02 belongs to the second generation of NavIC satellites, developed to enhance India’s regional navigation system.
- The satellite has an approximate weight of 2,232 kg, making it one of the heavier navigation satellites in ISRO’s fleet.
- It carries an advanced navigation payload that supports L1, L5, and S-band signals, ensuring improved accuracy and reliability for users.
- Designed for a mission life of over 12 years, the satellite is expected to provide long-term navigation services.
- One of its key features is the inclusion of a Rubidium Atomic Clock, which significantly enhances timing accuracy for precise positioning applications.
Significance of NVS-02 in NavIC System
- NavIC (Navigation with Indian Constellation) is India’s independent satellite navigation system, developed for precise location-based services.
- NVS-02 was meant to replace the aging IRNSS-1G satellite and strengthen NavIC’s performance.
- It enhances India’s strategic and technological autonomy in satellite-based navigation.
