Satellite Use: AsiaSat 9, AsiaSat’s most powerful satellite, is designed to deliver significantly improved power and higher bandwidth usage to generate higher efficiency for customers’ services. It is a replacement satellite for AsiaSat 4 at 122°E with multiple C, Ku and Ka-Band payloads. It carries the world’s first dedicated Ku-band Myanmar beam, new Ku-band beams for Indonesia and Mongolia, in addition to two enhanced Ku-band beams serving Australasia and East Asia and a wider high-power C-band coverage across the Asia-Pacific region. The five Ku-band beams onboard AsiaSat 9 are equipped with cross-strap beam switching capability to provide flexible coverage.

Satellite Statistics: __Multiple C, Ku and Ka-Band payloads __Orbital location: 122 degrees East __Anticipated service life: 15+ years

Mission Profile: The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at the Baikonur Cosmodrome in Kazakhstan, with the AsiaSat 9 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 AsiaSat 9 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 nearly circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geosynchronous transfer orbit. Separation of the AsiaSat 9 satellite is scheduled to occur approximately 9 hours, 13 minutes after lift-off.
