The State Commission has decided to roll out PROTON-M space rocket with YAMAL-42 spacecraft to launching complex. / December 7, 2012 /

At the Baikonur Cosmodrome the meeting of the State Commission took place which examined the results of preparation for launch of the Proton-M rocket (ILV) with Breez-M upper stage and Yamal-402 communication spacecraft. Based upon the supervisors’ reports the State Commission decided the ILV ready for rolling out to launching complex.

The ILV Proton-M transportation to launching complex is scheduled for December 5.

The Yamal-402 telecommunication satellite will replenish the home communication satellite constellation and provide fixed communication and transmission services over Russia, Western and Central Europe, the Middle East, and Northern Africa.

The spacecraft is equipped with twelve standard Ku-band 72MHz and sixteen 54MHz transponders as well as with eighteen „planned“ Ku-band 36MHz transponders. So, the total Yamal-402 satellite capacity will be 46 physical transponders or 66 equivalent 36MHz transponders.

The spacecraft antennas form four fixed beams: the Russian, Northern, European, and Southern, beams as well as one redirected beam.

The „planned“ bands (eighteen 36MHz transponders) will be used in the Russian beam which contours exactly the Russian borders. Four 54MHz transponders with standard bandwidths will be operated in the Russian beam in addition.

In the wider Northern beam covering the visible territory of the Russia, GIS-countries, nearly the whole Europe and a part of the Middle East, from nine to twelve 72MHz transponders will be operated.

Four 54MHz transponders will be used in the European beam that covers the territory of the Western and Central Europe, the Middle East, and Northern Africa.

The wide Southern beam covering the African territory to the south of Sahara will operate eight 54MHz transponders.

The beam formed by the antenna capable of redirecting on ground command during the spacecraft operation in orbit, may use up to three 72MHz transponders.

The Yamal-402 telecommunication spacecraft has been produced under the Gazprom Space Systems order.
