ICEYE-X39

ICEYE-X39 is an active satellite operated by FAB / ICEYE (Brazil), launched on 2024-08-16 from Vandenberg Space Force Base, United States on the Transporter-11 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 557 km and 575 km with an inclination of 97.7°. It travels at approximately 27,289 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. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks ICEYE-X39 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

ICEYE-X39 orbits at an average altitude of 566 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-X39’s average altitude, there are currently 1,083 active payloads and 512 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 5.7% of all active satellites. With an inclination of 97.7°, ICEYE-X39 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-X39.
