Türksat 1B was launched by Arianespace atop an Ariane-44LP H10+ launch vehicle, along with Brazilian satellite Brasilsat B1, in a dual-payload launch on August 10, 1994 at 23:05 UTC from ELA-2 at the Guiana Space Centre in Kourou, French Guiana. The satellite was successfully placed into geostationary transfer orbit and positioned at 42°E.[1][2][3][4]

It is based on the Aerospatiale Spacebus 2000 series having an on-orbit mass of about one ton. The communications payload consists of 16 Ku band transponders with six wideband channels of 72 MHz and ten narrowband of 36 MHz.[2]

In addition to Turkey, the satellite covered a geographical range from Europe to Central Asia before completing its mission in 2006.[4]
