SAR LUPE 2

SAR LUPE 2 is an active satellite operated by Armed Forces (Germany), launched on 2007-07-02 from PKMTR on the SAR-Lupe 2 launch. After 19 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 393 km and 402 km with an inclination of 98.1°. It travels at approximately 27,626 km/h (7.67 km/s), completing one full orbit every 93 minutes — that’s roughly 15.57 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 months to ~1 year. Orbital Radar tracks SAR LUPE 2 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

SAR LUPE 2 orbits at an average altitude of 398 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 SAR LUPE 2’s average altitude, there are currently 1,270 active payloads and 87 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1020. This makes it one of the more crowded altitude bands, containing roughly 7.1% of all active satellites. With an inclination of 98.1°, SAR LUPE 2 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. Germany operates approximately 87 active satellites in total, of which 9 share a similar altitude band with SAR LUPE 2.
