Türksat 1A, 1B, 1C

Türksat 1A [Aerospatiale]

Turkey had hoped by launching two GEO communications satellites to form an "instant" network. But Turksat 1A was lost on 24 January 1994 in an Ariane-44LP H10+ launch failure. Turksat 1B succeded on its launch on 10 August of the same year and was successfully positioned at 42 degrees E.

The spacecraft is based on the Aerospatiale Spacebus-2000 series with an on-orbit mass of slightly more than one metric ton. The communications payload consists of 16 Ku-band transponders with an expected operational life of 10 years or more. A contract for Turksat 1C to replace Turksat 1A was signed with Aerospatiale in 1994 for a launch in 1996.
