The system, called GPS Aided GEO Augmented Navigation, became fully operational in 2015.
It works with 15 ground stations, two control centres and three uplink stations across India.
It connects with similar systems from the United States, Europe and Japan.
India’s own regional navigation system NavIC works together with this satellite system.
Three Indian geostationary satellites broadcast corrected signals and safety information.
Pilots used this system in June 2026 to land a commercial jet using a satellite‑guided approach.
The technology can also be used for ships, road travel, trains and disaster relief.
