📖 About This Object
RADUGA 28 is an active satellite operated by Russia (CIS), launched on 1991-12-19 from Baikonur, Kazakhstan. With over 35 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 35,763 km and 35,792 km with an inclination of 13.4°. It travels at approximately 11,071 km/h (3.08 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 orbits per day. It is part of the Geo Protected constellation group. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks RADUGA 28 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
RADUGA 28 occupies geostationary orbit (GEO) at approximately 35,786 km above the equator. At this precise altitude, the satellite’s orbital period matches the Earth’s rotation — so it appears to hover over a fixed point on the equator. GEO is used primarily for broadcast television, weather monitoring (Meteosat, GOES) and wideband communications. Only about 560 active satellites occupy the GEO belt, but its commercial value is immense: a single GEO slot can cover roughly one-third of the Earth’s surface. This satellite has a non-zero inclination of 13.4°, meaning it traces a small figure-of-eight pattern relative to the ground rather than remaining perfectly stationary. This can indicate an aging satellite whose stationkeeping fuel is running low, or a deliberate inclined-orbit strategy to extend operational life.
RADUGA 28 orbits at approximately 35,778 km altitude, where the orbital period matches the Earth’s 24-hour rotation. This means it stays above the same point on the equator at all times. Its actual speed is still 11,071 km/h — it just keeps pace with the ground below. With an inclination of 13.4°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed.
RADUGA 28 is operated by Russia (CIS). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 21821. You can track RADUGA 28 in real time on Orbital Radar’s live tracker.
RADUGA 28 was launched on 1991-12-19 from Baikonur, Kazakhstan, the world’s first and largest operational space launch facility, located in Kazakhstan.
Yes — Orbital Radar tracks RADUGA 28 (NORAD ID 21821) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time.
RADUGA 28 travels at approximately 11,071 km/h (6,879 mph) — roughly 3.08 km/s. Despite this high speed, it appears stationary from the ground because it matches the Earth’s rotation. Geostationary satellites are actually slower than LEO satellites because orbital velocity decreases with altitude.
RADUGA 28 is a member of the Geo Protected constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Geo Protected satellites on Orbital Radar’s live tracker.
