Summary
TURKSAT 4B is a communication satellite, officially designated as 2015-060A with NORAD_CAT_ID 40984, launched on October 16, 2015, from the Tyuratam Site LC200/39 using a Proton-M/Briz-M launch vehicle. It measures 6.2 meters in length and has a diameter of 3.8 meters with a span of 25.3 meters. The satellite's dry mass is 2,500 kilograms, while its launch mass was 4,928 kilograms. Equipped with 18 Ku-band transponders, 24 Ka-band transponders, and 1 C-band transponder for communication purposes, TURKSAT 4B is powered by two deployable solar arrays and batteries. The satellite's design includes a box shape with two panels and uses an R-4D-11-164 motor. Manufactured by MELCO and owned by TURKS (Turkish Satellite Communications), the satellite has a designed lifetime of 15 years, though it carries fuel for up to 20 years.
