ICEYE-X43

ICEYE-X43 is an active satellite operated by ICEYE (Brazil), launched on 2024-08-16 from Vandenberg SFB, California. It orbits in Low Earth Orbit (LEO) at altitudes between 562 km and 574 km with an inclination of 97.7°. It travels at approximately 27,285 km/h (7.58 km/s), completing one full orbit every 96 minutes — that’s roughly 15.00 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 ~3–10 years. Orbital Radar tracks ICEYE-X43 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

ICEYE-X43 orbits at an average altitude of 568 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-X43’s average altitude, there are currently 3,149 active payloads and 475 tracked debris or rocket body fragments — notable neighbours include STARLINK-1184, STARLINK-1276, ONEWEB-0050. This makes it one of the more crowded altitude bands, containing roughly 18.1% of all active satellites. With an inclination of 97.7°, ICEYE-X43 passes over latitudes between 97.7°N and 97.7°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. Brazil operates approximately 31 active satellites in total, of which 2 share a similar altitude band with ICEYE-X43.
