The satellite is equipped with two 3-panel solar arrays for power generation, a chemical propulsion system for apogee maneuvers and orbital adjustments and navigation and stabilization equipment. Turksat 4A carries a communication payload consisting of 2 Ka-Band and 28 Ku-Band transponders as well as C-Band transponders and an X-Band payload for use by the Turkish military.
Stationed at 42 degrees East in Geostationary Orbit, Turksat 4A will provide coverage to Africa, Europe, the middle East and South and Central Asia with spotbeam coverage of Turkey. Turksat 4A will provide TV broadcasting and communication services for commercial and government customers.
