ILS Readies For Proton M Launch Of TURKSAT-4B To Provide Telecommunication + DTV Over Continents


[Satnews] On October 17, the ILS Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the TURKSAT-4B satellite on board.

The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the TURKSAT-4B satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission maneuvers to advance the orbital unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geostationary transfer orbit. Separation of the TURKSAT-4B satellite is scheduled to occur approximately 9 hours, 13 minutes after liftoff.

TURKSAT-4B is a commercial communication satellite built by Mitsubishi Electric. The satellite will 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.

TURKSAT-4B will be positioned at 50 degrees east longitude and consists of multiple transponders with an expected on-orbit maneuver life of 30 years. TURKSAT-4B satellite will expand the space capacity of Turkey and provide enhanced performance to its coverage areas. The satellite will provide high flexibility of switchability and connectivity among different service areas to its customers.
