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 v1.2 (Block 5) launch vehicle of SpaceX at Cape Canaveral, U.S. in June 2021.

Features

Türksat 5B is a communications satellite to serve on a geostationary orbit at 42° East longitude.[1] It was built on a Eurostar E3000EOR satellite bus manufactured by Airbus Defence and Space.[1][2] It will have a mass of about 4,500 kg (9,900 lb) and an expected on-orbit life time of 15 years. Powered by two deployable solar panels and batteries at 15 kW,[1] the high-throughput satellite with 50 Gbps will consist of Ku- and Ku-band.[3]
