ICEYE-X11

ICEYE-X11 is an active satellite operated by ICEYE Ltd. (Finland), launched on 2021-06-30 from Cape Canaveral, Florida. It orbits in Low Earth Orbit (LEO) at altitudes between 266 km and 269 km with an inclination of 97.6°. It travels at approximately 27,896 km/h (7.75 km/s), completing one full orbit every 90 minutes — that’s roughly 16.03 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 weeks to months. Orbital Radar tracks ICEYE-X11 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

ICEYE-X11 orbits at an average altitude of 268 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 ICEYE-X11’s average altitude, there are currently 163 active payloads and 4 tracked debris or rocket body fragments — notable neighbours include STARLINK-1151, STARLINK-1143, STARLINK-1280. With an inclination of 97.6°, ICEYE-X11 passes over latitudes between 97.6°N and 97.6°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. Finland operates approximately 30 active satellites in total, of which 2 share a similar altitude band with ICEYE-X11.
