OPS 2366 (TRANSIT 14)

OPS 2366 (TRANSIT 14) is an active satellite operated by USN NAVAIR (United States), launched on 1966-08-18 from Vandenberg Space Force Base, United States on the NNS O-10 launch. After more than 60 years in orbit, it is one of the longest-surviving objects in the space catalogue. It orbits in Low Earth Orbit (LEO) at altitudes between 1,035 km and 1,081 km with an inclination of 88.8°. It travels at approximately 26,370 km/h (7.32 km/s), completing one full orbit every 106 minutes — that’s roughly 13.54 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~500–1,000 years. Orbital Radar tracks OPS 2366 (TRANSIT 14) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OPS 2366 (TRANSIT 14) orbits at an average altitude of 1,058 km in the upper LEO band, where atmospheric drag is negligible and objects can persist for centuries to millennia. This altitude is used by broadband constellations like OneWeb and by scientific missions requiring stable orbits far from the densest debris bands. Within ±50 km of OPS 2366 (TRANSIT 14)’s average altitude, there are currently 310 active payloads and 605 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0041. With an inclination of 88.8°, OPS 2366 (TRANSIT 14) passes over latitudes between 88.8°N and 88.8°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. United States operates approximately 13,279 active satellites in total, of which 43 share a similar altitude band with OPS 2366 (TRANSIT 14).
