Cosmos 381



Cosmos 381, termed by the USSR as an orbital laboratory, had a well described mission involving the downward vertical pulse probing of the ionosphere. A variety of instruments were used and the result stored on board for subsequent readout while in radio visibility of measuring centers on earth. The payload was controlled by some unspecified means to prevent disorderly spinning of the satellite. Other sensors determined its precise position in orbit and angular position in relation to the sun and the earth's magnetic field. After the fact, Cosmos 381 was identified as an ionspheric topside sounder.
