STUDSAT

STUDSAT is an active satellite operated by NMIT Bangalore (India), launched on 2010-07-12 from Satish Dhawan Space Centre, India on the PSLV Rideshare 03 launch. After 16 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 542 km and 556 km with an inclination of 98.1°. It travels at approximately 27,322 km/h (7.59 km/s), completing one full orbit every 96 minutes — that’s roughly 15.06 orbits per day. Its near-polar, sun-synchronous orbit means it passes over any given point on Earth at approximately the same local solar time, ideal for consistent Earth observation lighting conditions. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks STUDSAT in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

STUDSAT orbits at an average altitude of 549 km in a sun-synchronous orbit (SSO), a specialised subset of LEO where the orbital plane precesses to maintain a constant angle relative to the Sun. This provides consistent lighting conditions on every pass — essential for Earth observation, weather monitoring and environmental science. Within ±50 km of STUDSAT’s average altitude, there are currently 1,371 active payloads and 399 tracked debris or rocket body fragments — notable neighbours include STARLINK-1184, STARLINK-1276, ONEWEB-0050. This makes it one of the more crowded altitude bands, containing roughly 7.2% of all active satellites. With an inclination of 98.1°, STUDSAT passes over latitudes between 98.1°N and 98.1°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. India operates approximately 108 active satellites in total, of which 20 share a similar altitude band with STUDSAT.
