NavIC
India's Regional Navigation Satellite System
Navigation with Indian Constellation (NavIC), formerly IRNSS (Indian Regional Navigation Satellite System), is India's autonomous satellite-based navigation system developed by ISRO. It provides precise Positioning, Velocity, and Timing (PVT) information across India and up to 1,500 km beyond its borders — covering the Indian Ocean region. NavIC is strategically significant as it reduces India's dependence on the US-controlled GPS (Global Positioning System).
- Full name: Navigation with Indian Constellation (NavIC); earlier called IRNSS
- Constellation: 7 operational satellites (3 in geostationary orbit at 32.5°E, 83°E, 131.5°E; 4 in geosynchronous inclined orbit)
- Coverage: India and surrounding region up to 1,500 km; horizontal position accuracy: better than 20 metres (SPS)
- Two services: Standard Positioning Service (SPS) — open to civilians; Restricted Service (RS) — encrypted, for military and strategic use
- NVS series (second generation): incorporates indigenous atomic clocks (rubidium); NVS-01 launched May 2023, NVS-02 launched January 2025
- NVS-02 mission: was to replace IRNSS-1E (launched 2016) at the 111.75°E geostationary slot
