Development

The Türksat 5B project started in September 2011.[1] The final production contract for the Turkish Aerospace Industries (TAI) was planned for 2015. After a delay, the contract was realized in October 2017 when the Airbus Defence and Space was selected to join the project with 25% for building the satellite in Turkey, which was a major stimulation.[1][2]

In November 2020, it was announced that satellite level tests for Türksat 5B have begun. It is planned that the satellite will be launched with a Falcon 9 launch vehicle of SpaceX at Cape Canaveral, Florida, on 19 December 2021.[3] The Falcon 9 booster used on this mission is B1052.3, that is, a Falcon Heavy side booster turned into a Falcon 9 first stage booster.

Spacecraft

Türksat 5B is a communications satellite to serve on a geostationary orbit at 42° East longitude.[1] It was built on a Eurostar-3000EOR satellite bus manufactured by Airbus Defence and Space.[1][2] It will have a mass of 4,500 kg (9,900 lb) and an expected design lifetime of 15 years, maneuover lifetime of more than 35 years. Powered by two deployable solar panels and batteries at 15 kW,[1] the 50 Gbps high-throughput satellite will consist of Ku-band, Ka-band and X-band transponders.[4]

The 3 military X-band transponders have global coverage and were developed by Aselsan for use by the Turkish Presidency of Defense Industries (SSB/SSM).[5][6]
