Overview
According to the in-orbit delivery contract signed in early 2011, Mitsubishi Electric (MELCO) of Japan is in charge of the construction of the satellite's base MELCO DS2000, and the American-Russian joint-venture company International Launch Services (ILS) will provide the launch of the spacecraft atop a Russian Proton-M space launch vehicle from Baikonur Cosmodrome in Kazakhstan scheduled in late 2014. In the scope of the contract, Turkish engineers will collaborate in the production of the satellite. The production of Türksat 4B at the Mitsubishi Electric Facility in Kamakura was completed in June 2014.
Türksat 4B is part of the Turksat series of satellites, and will be placed in geosynchronous orbit at 50°E to provide telecommunication and direct TV broadcasting services over a wide geographic region between west of China and east of England spanning Turkey, as well as Europe, Central Asia, the Middle East and Africa.
Türksat 4B will have a mass of approximately 4,924 kg (10,856 lb) and an expected on-orbit life time of 15 years.
Türksat 4A and Türksat 4B are projected to enable a capacity increase because the satellites currently in service, namely Türksat 2A and Türksat 3A, are at 90% occupied.
Control of UAV's by SATCOM
The Turkish Armed Forces will have dedicated channels on the Turksat 4B for use in guidance of it SATCOM equipped Anka-S UCAV systems.
