Türksat 4B is a Turkish communications satellite, operated by Türksat.

Overview

According to the in-orbit delivery contract signed in early 2011, Mitsubishi Electric (MELCO) of Japan was in charge of the construction of the satellite's base MELCO DS2000,[1] and the American-Russian joint-venture company International Launch Services (ILS) provided 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 collaborated in the production of the satellite.[2][3][4][5] The production of Türksat 4B at the Mitsubishi Electric Facility in Kamakura was completed in June 2014.[6]

Türksat 4B is part of the Turksat series of satellites, and is 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.[3][4][7]

Türksat 4B has a mass of approximately 4,924 kg (10,856 lb) and an expected on-orbit life time of 15 years.[4][8][9]

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.[3][10]

Control of UAV's by SATCOM

The Turkish Armed Forces has dedicated channels on the Turksat 4B for use in guidance of it SATCOM equipped Anka-S UCAV systems.[11][12]

Launch

The spacecraft was launched by the American-Russian joint-venture company International Launch Services (ILS) atop a Russian Proton-M space launch vehicle on October 16, 2015, at 20:40:00 from Baikonur Cosmodrome Pad 39 in Kazakhstan.[13][9]

After successfully completing the testing process, the satellite was placed on its final orbit on October 24, 2015.[14]

Features

Türksat 4B provides expansion of Ka band's 3-Gbps data transfer capacity at spot coverage areas through its 1,800 MHz bandwidth in total. A total of 792 MHz communication capacity is secured by 18 transponders of the Ku band.[14]
