ICEYE-X63

ICEYE-X63 is an active satellite operated by ICEYE (Finland), launched on 2026-01-11 from Vandenberg SFB, California. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 599 km and 607 km with an inclination of 97.8°. It travels at approximately 27,216 km/h (7.56 km/s), completing one full orbit every 97 minutes — that’s roughly 14.88 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 ~10–25 years. Orbital Radar tracks ICEYE-X63 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

ICEYE-X63 orbits at an average altitude of 603 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-X63’s average altitude, there are currently 1,619 active payloads and 673 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 9.3% of all active satellites. With an inclination of 97.8°, ICEYE-X63 passes over latitudes between 97.8°N and 97.8°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 12 share a similar altitude band with ICEYE-X63.
