NANOFF A

NANOFF A is an active satellite operated by TUB (Germany), launched on 2023-12-01 from Vandenberg Space Force Base, United States on the Korea 425 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 521 km and 535 km with an inclination of 97.5°. It travels at approximately 27,364 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. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks NANOFF A in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

NANOFF A orbits at an average altitude of 528 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 NANOFF A’s average altitude, there are currently 5,017 active payloads and 307 tracked debris or rocket body fragments — notable neighbours include STARLINK-1184, STARLINK-1276, STARLINK-1451. This makes it one of the more crowded altitude bands, containing roughly 26.8% of all active satellites. With an inclination of 97.5°, NANOFF A passes over latitudes between 97.5°N and 97.5°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 93 active satellites in total, of which 29 share a similar altitude band with NANOFF A.
