Launch Site:
Baikonur Cosmodrome, Kazakhstan
Launch Pad 24

Launch Customer:  
Gazprom Space Systems, Moscow, Russia

Satellite Manufacturer:      
Prime: JSC ISS Reshetnev, Krasnoyarsk, Russia
Sub-Prime: Thales Alenia Space, Cannes, France

Launch Vehicle Manufacturer:

Launch Services Provider:
International Launch Services, Reston, VA

Satellite Use:
At an orbital location of 90 degrees East longitude, the Yamal-401 communications satellite will provide services to users in Russia and CIS countries. The combined payload of the satellite will include 17 x 72 MHz transponders in standard C-band, 18 x 72 MHz transponders in standard Ku-band and 18 x 36 MHz transponders in planned frequencies of Ku-band. The total capacity of the Yamal-401 satellite will amount to 53 physical transponders or 88 equivalent (36 MHz) transponders, which will compose 1 fixed beam in C-band covering Russia and CIS countries and 2 fixed beams in Ku-band (Russian and Northern). JSC Gazprom Space Systems has ensured the development of the ground infrastructure to control and operate the satellite. With the addition of the Yamal-401 satellite into the company’s orbital constellation, JSC Gazprom Space Systems will strengthen its position in the global space communications market.

Satellite Statistics:  
__53 physical transponders or 88 equivalent (36 MHz) transponders
__Planned orbital location: 90° East longitude
__Anticipated service life: 15 years

Mission Profile:       
The Proton M launch vehicle, utilizing a 4-burn Breeze M mission design, will lift off from Pad 24 at Baikonur Cosmodrome, Kazakhstan, with the Yamal-401 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 Yamal-401 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 geosynchronous orbit. Separation of the Yamal-401 satellite is scheduled to occur approximately 9 hours, 1 minute after liftoff.

Target Orbit at Separation:
Perigee:  35,669 km
Apogee: 35,669 km
Inclination: 0.0 degrees

Spacecraft Separation:      
Approximately 9 hours, 1 minute after liftoff
