Class: Earth. Type: Magnetosphere. Nation: Ukraine. Agency: MO SSSR. Manufacturer: Yuzhnoye.

Measurements of the sun; used for Interkosmos launches. Payload included East European experiments to study solar UV, X-ray effects on upper atmosphere. Investigation of solar radiation and its effect on the atmosphere of the earth.

Design work began in April 1967. Adaptation of DS satellites by KB Yuzhnoye. For the Interkosmos modifications V F Chutkin was Chief Designer and First Assistant was V S Budnik. Interkosmos-1 was launched by a Kosmos-2 launch vehicle in October 1969.
