TSAT-1A

TSAT-1A is an active satellite operated by India, launched on 2024-04-07 from Cape Canaveral, Florida. It orbits in Low Earth Orbit (LEO) at altitudes between 454 km and 468 km with an inclination of 45.6°. It travels at approximately 27,498 km/h (7.64 km/s), completing one full orbit every 94 minutes — that’s roughly 15.35 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks TSAT-1A in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

TSAT-1A orbits at an average altitude of 461 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of TSAT-1A’s average altitude, there are currently 7,969 active payloads and 173 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1017. This makes it one of the more crowded altitude bands, containing roughly 45.7% of all active satellites. With an inclination of 45.6°, TSAT-1A passes over latitudes between 45.6°N and 45.6°S, covering the tropical and temperate zones where most of the world’s population resides. Low-to-mid inclination orbits are efficient to reach from equatorial and mid-latitude launch sites. India operates approximately 108 active satellites in total, of which 10 share a similar altitude band with TSAT-1A.
