Satellite Use:                        
As part of Intelsat’s 2012 fleet replacement and expansion plans, Intelsat 22 will carry two Ku-band mobility beams providing coverage of the Indian Ocean region, which will blanket busy maritime and aeronautical routes. From its position at 72 degrees East, Intelsat 22 will have Ku-band capacity serving the Middle East and eastern Africa. Its C-band hemi beams coverage will provide connectivity to and from most of Europe, Africa, the Middle East and eastern Asia.
 
It also carries an Ultra-High Frequency hosted payload that will be used by the Australian Defence Force. The satellite is the first to utilize Boeing’s new 702MP platform

Satellite Statistics:              
__48 C-band transponders
__24 Ku-band transponders
__18 UHF transponders
__Planned orbital location: 72 degrees east longitude
__Anticipated service life: 18 years

Mission Profile:                    
This is the first supersynchronous mission for ILS Proton. The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the Intelsat 22 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 Intelsat 22 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 Intelsat 22 satellite is scheduled to occur approximately 15 hours, 30 minutes after liftoff.
