About COSMOS 381

COSMOS 381 is a satellite from Russia (or the former Soviet Union), launched on Dec 2, 1970 from Plesetsk Missile and Space Complex.

It circles Earth every 105 minutes (13.8 times a day), between 959 and 1,004 km up, on an orbit tilted 74.0° to the equator, so its path covers latitudes up to 74° north and south.

The map shows where it is right now; the pass list tells you when it next comes over your location.

Orbit height over the past year

Over the last 10 days its lowest point went from 959 km to 959 km. Sudden rises are engine burns that lift the orbit; slow declines are drag from the thin upper atmosphere.
