Türksat 1C was a Turkishcommunications satellite as part of a project to form an instant network with twogeosynchronous satellites that is supervised by the companiesTürksat A.Ş. in Turkey andAérospatiale of France.[1]
Türksat 1C was launched byArianespace atop anAriane-44L H10-3 launch vehicle along withSaudi Arabian satelliteArabsat-2A in a dual-payload launch on July 9, 1996, fromELA-2 at theGuiana Space Centre inKourou,French Guiana. It was built under the insurance terms of the turnkey system contract to replace the first Turkish satelliteTürksat 1A, which was lost following a launch failure on January 24, 1994. The contract was modified so that the coverage area of Türksat 1C was enlarged by two big zones.[2][3]
Turksat 1C was successfully placed intogeostationary transfer orbit and positioned at 31.3°E on July 10, 1996. Completing the orbital tests, the satellite shifted to longitude42°E. After this process, which took 17 days, the broadcast traffic of theTürksat 1B was transferred to Türksat 1C. Finally, when these processes completed Türksat 1B was positioned at 31.3°E following similar orbital manoeuvres.
Turksat 1C was designed for covering Turkey and Europe on west spot by vertical emission and Turkey and Central Asia on east spot by horizontal emission so as to serve simultaneously between Europe, Turkey and Central Asia, and to provide direct connection between Europe and Central Asia. It is based on theAerospatialeSpacebus 2000 series having an on-orbit mass of 1,062 kg (2,341 lb).[1] The communications payload consists of 16Ku bandtransponders with eightbackup, nine with 36Mhz, two with 54Mhz and five 72Mhz bandwidth.[2][4]
On July 16, 2008, all traffic on Turksat 1C was transferred toTurksat 3A, which was launched on June 13, 2008[5] and its television broadcast was terminated on October 3, 2010.
