AAC-AIS-SAT2

AAC-AIS-SAT2 is an active satellite operated by United Kingdom, launched on 2023-06-12 from Vandenberg SFB, California. It orbits in Low Earth Orbit (LEO) at altitudes between 571 km and 653 km with an inclination of 98.2°. It travels at approximately 27,199 km/h (7.56 km/s), completing one full orbit every 97 minutes — that’s roughly 14.86 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 ~10–25 years. Orbital Radar tracks AAC-AIS-SAT2 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

AAC-AIS-SAT2 orbits at an average altitude of 612 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 AAC-AIS-SAT2’s average altitude, there are currently 1,586 active payloads and 725 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3005, STARLINK-3090. This makes it one of the more crowded altitude bands, containing roughly 9.1% of all active satellites. With an inclination of 98.2°, AAC-AIS-SAT2 passes over latitudes between 98.2°N and 98.2°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 Kingdom operates approximately 720 active satellites in total, of which 17 share a similar altitude band with AAC-AIS-SAT2.
