Cosmos 381 (Russian: Космос 381) artificial satellite provided data on the physical characteristics of the layers of the Earth's Ionosphere using a Mayak radio transmitter. The study covered almost the entire global surface.
Launch
The satellite was launched into a Low Earth Orbit by a Kosmos-3 rocket (11K65M) from the LC–132/2 starting point at Plesetsk Cosmodrome on the 2nd of December, 1970.
Orbit
Orbit was 971km at periapsis and 1013km at apoapsis. Inclination 74 degrees. Decay into the Earth's atmosphere is expected after about 1,200 years.
