INSAT 2E (APR-1)

INSAT 2E (APR-1) is an active satellite operated by ISRO (India), launched on 1999-04-02 from Guiana Space Centre, French Guiana on the Insat 2E launch. With over 27 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,921 km and 36,002 km with an inclination of 11.6°. It travels at approximately 11,047 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 INSAT 2E (APR-1) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

INSAT 2E (APR-1) 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 11.6°, 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 INSAT 2E (APR-1)’s average altitude, there are currently 67 active payloads and 21 tracked debris or rocket body fragments. India operates approximately 111 active satellites in total, of which 4 share a similar altitude band with INSAT 2E (APR-1).
