Yamal-402 is large-sized satellite.
The payload power of this satellite
is more than 10 kW.
Satellite is planned to launch in 2012.
Its lifetime is 15 years.
Yamal-402 satellite will be launched to the orbital position 55°E.
Twelve and sixteen standard Ku-band 72 MHz and 54 MHz transponders respectively and eighteen “planned” Ku-
6 MHz transponders are installed on the satellite. So, the total Yamal-402 capacity will be 46 transponders or 66 equivalent 36 MHz transponders.
Satellite antennas form 4 fixed beams: Russian, Northern, European, Southern, and one steerable beam.
«Planned» bandwidth (eighteen 36 MHz transponders) will be operated in Russian beam, which exactly contours the Russian borders. Additionally four 54 MHz transponders with standard bandwidth will be operated in Russian beam.
From nine to twelve 72 MHz transponders will be operated in more wide Northern beam which covers the visible part of Russia, CIS countries, almost all Europe and part of Middle East.
Four 54 MHz transponders will be operated in European beam, which covers East and Central Europe, Middle East and Northern Africa.
Eight 54 MHz transponders will be operated in wide Southern beam, which covers the territory of Africa to the south of Sahara.
Up to three 72 MHz transponders may be operated in the beam formed by antenna, which can be steered through the commands from the earth while the satellite is in service.
There is a possibility of interbeam connection of Southern beam with Russian and European, and Northern beam with steerable beam.
