SICH 2

SICH 2 is an active satellite operated by DKAU (Ukraine), launched on 2011-08-17 from Yasny / Dombarovsky, Russia on the Dnepr Rideshare 7 launch. After 15 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 667 km and 682 km with an inclination of 97.8°. It travels at approximately 27,078 km/h (7.52 km/s), completing one full orbit every 98 minutes — that’s roughly 14.66 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 ~10–25 years. Orbital Radar tracks SICH 2 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

SICH 2 orbits at an average altitude of 675 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 SICH 2’s average altitude, there are currently 699 active payloads and 1,316 tracked debris or rocket body fragments — notable neighbours include TERRA, AQUA, ONEWEB-0179. With an inclination of 97.8°, SICH 2 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. Ukraine operates approximately 4 active satellites in total.
