The Soviet-era Orion satellites launched within the Cosmos programme were the first recoverable cartographic satellites to be flown by the Soviet Union. Few details of the programme are available, but this paper reviews what is known and what can be obtained from an analysis of the orbital data issued via the Goddard Space Flight Center's Orbit Information Group.
