Yamal-300К was launched in 2012. It is a middle-size spacecraft. The payload power is 5.6 kW. Yamal-300К satellite is in the 183°E orbital position.
The satellite is fitted with a combined payload, including 11 C-band 72 MHz transponders and 18 Ku-band 72 MHz transponders.
To operate in C-band there is an Rx/Tx antenna installed on Yamal-300K satellite, which forms a fixed contoured beam.
Ku-band antennas, installed on the satellite, form three beams: one fixed contoured beam (Northern beam 1), one fixed elliptic beam (Northern beam 2) and one steerable beam.
Northern beam 1 covers eastern territory of Russia, northern part of Pacific Ocean and western territory of Northern America. Six transponders are operating in this beam.
Northern beam 2 covers the eastern part of Russia. Nine transponders are operating in this beam.
The steerable beam can be moved with the commands from the earth while the satellite is in service. Three transponders are operating in this beam.
The Yamal-300K satellite was launched by Proton vehicle together with satellite of another operator on 3 November, 2012
