Mission Profile: The Proton launch vehicle will inject the satellite into geosynchronous transfer orbit, using a five-burn Breeze M mission design. The first three stages of the Proton will use a standard ascent trajectory to place the Breeze M fourth stage, with the satellite, into a suborbital trajectory, from which the Breeze M will place itself and the spacecraft into a circular parking orbit of 173 km (107.5 miles), inclined at 51.5 degrees. Then the satellite will be propelled to its transfer orbit by additional burns of the Breeze M. Following separation from the Breeze M, the spacecraft will perform a series of liquid apogee engine burns to raise perigee, lower inclination and circularize the orbit at geostationary altitude.

Target Orbit at Separation:
Apogee: 35,786 km (22,236 miles)
Perigee: 3,200 km (1,988 miles)
Inclination: 9.1 degrees

Spacecraft Separation: Approximately 9 hours, 11 minutes after liftoff

ILS Mission Statistics:
7th ILS mission this year
3rd ILS Proton mission this year
30th ILS mission on Proton
308th Proton mission overall
