📖 About This Object
OPS 9442 (DSCS 2-12) is an active satellite operated by United States, launched on 1978-12-14 from Cape Canaveral, Florida. With over 48 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,291 km and 36,325 km with an inclination of 8.3°. It travels at approximately 11,002 km/h (3.06 km/s), completing one full orbit every 24.4 hours — that’s roughly 0.98 orbits per day. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks OPS 9442 (DSCS 2-12) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
OPS 9442 (DSCS 2-12) 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 8.3°, 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.
❓ Frequently Asked Questions
OPS 9442 (DSCS 2-12) orbits at approximately 36,308 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 11,002 km/h — it just keeps pace with the ground below. With an inclination of 8.3°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed.
OPS 9442 (DSCS 2-12) is operated by United States. It is catalogued by the U.S. Space Surveillance Network under NORAD ID 11145. You can track OPS 9442 (DSCS 2-12) in real time on Orbital Radar’s live tracker.
OPS 9442 (DSCS 2-12) was launched on 1978-12-14 from Cape Canaveral, Florida, one of the busiest launch facilities in the world, operated by NASA and the U.S. Space Force on Florida’s Atlantic coast.
Yes — Orbital Radar tracks OPS 9442 (DSCS 2-12) (NORAD ID 11145) 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.
OPS 9442 (DSCS 2-12) travels at approximately 11,002 km/h (6,836 mph) — roughly 3.06 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.
