This page contains philatelic information on the Interkosmos-series satellites. Catalog numbers, years of issue, and notes on the satellites featured are given when available. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.

The information provided must be prefaced by a disclaimer, in that factual information about Interkosmos-series satellites was, and still is, very hard to obtain. Some of the Interkosmos-series identifications may be speculative, or even incorrect and are therefore prefaced by "most-likely" or "possible" when they are questionable. The authors would appreciate any assistance in correcting or updating the information presented about Interkosmos-series satellites.

See also the closely-related and equally-challenging Kosmos-series satellites page.

In the table below, the items with Interkosmos descriptions that have yet to be verified are highlighted in pale yellow.

1Known fake cover, with a made-up Baikonur postmark, suspected to have been created by Boris Khoroshev from Moscow, and sold by a stamp dealer in Western Europe. There were no Baikonur Cosmodrome official postmarks until 1975 for the Apollo-Soyuz events. Reference the article written by Russian collector Oleg Vaisberg published as an Appendix called "Russian (Soviet) Space Covers" to Bruce Cranford's book Space Covers: Dictionary and Identifier. See also, an analysis of the situation in a book published in 2008 called Commemorative Space Covers from Collector Clubs of the Soviet Union, 1957 to 1980. Another indicator on these fakes is the use of a "first day" cachet that appears on most, but not all, of these fakes.
2IK-19 and Kosmos-1079 were launched on the same date, and at the same launch site, but on different rockets.
3The IK-1 series includes IK-1, 4, 7, 11, 14, and 16, all of which have a ds-u3-ik bus, as noted on the IK-series reference images page.
4AA no. = Tartuski Klub Kollektsionerov (TKK) [Tartu Collector Club] "Astronautika Annaalid" number. See Jim Reichman's Philatelic Study Report on Tartu Space Club Covers, 1962-1978, 2011. (e-mail: jgreichman (at) datawest.net).
