KHAYYAM

KHAYYAM is an active satellite operated by Revolutionary Guard Corps (Iran), launched on 2022-08-09 from Baikonur, Kazakhstan. It orbits in Low Earth Orbit (LEO) at altitudes between 487 km and 490 km with an inclination of 97.3°. It travels at approximately 27,443 km/h (7.62 km/s), completing one full orbit every 94 minutes — that’s roughly 15.26 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. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks KHAYYAM in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

KHAYYAM orbits at an average altitude of 489 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 KHAYYAM’s average altitude, there are currently 8,099 active payloads and 228 tracked debris or rocket body fragments — notable neighbours include STARLINK-1017, STARLINK-1039, STARLINK-1047. This makes it one of the more crowded altitude bands, containing roughly 46.5% of all active satellites. With an inclination of 97.3°, KHAYYAM passes over latitudes between 97.3°N and 97.3°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. Iran operates approximately 5 active satellites in total, of which 2 share a similar altitude band with KHAYYAM.
