IRNSS 1G

IRNSS 1G is an active satellite operated by Indian Space Research Organization (ISRO) (India), launched on 2016-04-28 from SRI. After 10 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Geostationary Orbit (GEO) at altitudes between 35,757 km and 35,820 km with an inclination of 5.2°. It travels at approximately 11,069 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks IRNSS 1G in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

IRNSS 1G occupies geostationary orbit at approximately 35,786 km above the equator, where its orbital period matches the Earth’s 24-hour rotation. From the ground, it appears to hover over a fixed point — ideal for broadcast television, weather monitoring and wideband communications. With an inclination of 5.2°, it traces a small figure-of-eight pattern relative to the equator rather than remaining perfectly stationary, which can indicate aging stationkeeping fuel or a deliberate inclined-orbit strategy. Within ±50 km of IRNSS 1G’s average altitude, there are currently 715 active payloads and 61 tracked debris or rocket body fragments — notable neighbours include ASTRA 1N, GOES 16, TDRS 13. India operates approximately 108 active satellites in total, of which 36 share a similar altitude band with IRNSS 1G.
