The first DS-U3-IK satellite was launched on 1969 Oct 14 by the 11K63 Kosmos launch vehicle from GTsP4 (Kapustin Yar). It was given the code name Interkosmos-1. Interkosmos-1 carried solar monitors built in the USSR, the GDR and Czechoslovakia. UV and X-ray detectors observed the sun directly, while an optical photometer looked at the setting or rising sun through the Earth's atmosphere to detect absorption by atmospheric aerosols.
