CYGFM01

CYGFM01 is an active satellite operated by University of Michigan/NASA Earth Science Technology Office (United States), launched on 2016-12-15 from Esrange, Sweden. After 10 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 390 km and 400 km with an inclination of 34.9°. It travels at approximately 27,632 km/h (7.68 km/s), completing one full orbit every 92 minutes — that’s roughly 15.57 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is months to ~1 year. Orbital Radar tracks CYGFM01 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

CYGFM01 orbits at an average altitude of 395 km in the lower reaches of Low Earth Orbit, where atmospheric drag is significant and orbital lifetimes are measured in months to a few years. This is the busiest corridor in space — home to crewed spacecraft, rapid-revisit imaging satellites and the densest part of the Starlink constellation. Within ±50 km of CYGFM01’s average altitude, there are currently 1,288 active payloads and 82 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1020. This makes it one of the more crowded altitude bands, containing roughly 7.4% of all active satellites. With an inclination of 34.9°, CYGFM01 passes over latitudes between 34.9°N and 34.9°S, covering the tropical and temperate zones where most of the world’s population resides. Low-to-mid inclination orbits are efficient to reach from equatorial and mid-latitude launch sites. United States operates approximately 12,360 active satellites in total, of which 1,134 share a similar altitude band with CYGFM01.
