Space HubNavIC (Navigation with Indian Constellation)
India's Sovereign Regional Navigation Satellite System
NavIC (IRNSS) is India's independent regional navigation satellite system developed by ISRO. Operating with a constellation of 7 active satellites in geostationary (GEO) and inclined geosynchronous (GSO) orbits, NavIC provides position accuracy better than 5 meters across India and a 1,500 km radius surrounding the subcontinent.
Development History & Milestones
Conceived after regional positioning access was restricted during critical national defense operations, ISRO initiated the IRNSS programme. The first satellite IRNSS-1A was launched in July 2013 aboard PSLV-C22. NavIC was officially designated for public and strategic applications in 2016.

Frequently Asked Questions
What is NavIC and how is it different from GPS?
NavIC is India's indigenous regional navigation system focused specifically on India and South Asia, providing higher accuracy (< 5 meters) in the region using dual L5 and S-band frequencies compared to global GPS.
Can consumer mobile phones use NavIC?
Yes, modern smartphones equipped with Snapdragon, MediaTek, and Apple chipsets support NavIC L5/L1 signal reception.
Which ISRO rocket launches NavIC satellites?
NavIC (IRNSS) satellites are primarily launched into geosynchronous transfer orbit using ISRO's PSLV-XL and GSLV Mk II launch vehicles.
