mal-401 is large-sized satellite. The payload power of this satellite
is more than 10 kW.
Satellite is planned to launch in 2014.
Its lifetime is 15 years.
Yamal-401 satellite will be launched to the 90°E orbital position.
Satellite combined payload consists of seventeen standard C-band 72 MHz, eighteen standard Ku-band 72 MHz and eighteen “planned” Ku-band 36 MHz transponders. So, the total Yamal-401 satellite capacity will be 53 transponders or 88 equivalent 36 MHz transponders.
A fixed contoured Russian/CIS beam is formed on Yamal-401 to operate in C-band.
Two fixed contoured beams are formed to operate in Ku-band
Northern beam covers not only all the visible territory of Russia but near-by countries too. The highest power of this beam will be focused on the most populated territory of Russia. Transponders with standard bandwidth (eighteen 72 MHz transponders) are planned to use in Northern beam.
Russian beam exactly contours the Russian borders. Transponders with “planned” bandwidth (eighteen 36 MHz transponders) will be operated in this beam.
