RANGE A

RANGE A is an active satellite operated by Georgia Institute of Technology (United States), launched on 2018-12-03 from Vandenberg SFB, California. It orbits in Low Earth Orbit (LEO) at altitudes between 519 km and 532 km with an inclination of 97.4°. It travels at approximately 27,369 km/h (7.60 km/s), completing one full orbit every 95 minutes — that’s roughly 15.13 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 ~3–10 years. Orbital Radar tracks RANGE A in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

RANGE A orbits at an average altitude of 526 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 RANGE A’s average altitude, there are currently 6,804 active payloads and 288 tracked debris or rocket body fragments — notable neighbours include STARLINK-1039, STARLINK-1184, STARLINK-1231. This makes it one of the more crowded altitude bands, containing roughly 39% of all active satellites. With an inclination of 97.4°, RANGE A passes over latitudes between 97.4°N and 97.4°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. United States operates approximately 12,360 active satellites in total, of which 6,135 share a similar altitude band with RANGE A.
