The Yamal-402 satellite is located in the orbital position 55В°E. Its total capacity is 66 equivalent 36 MHz transponders.
Of the satellite beams 4 are fixed (Russian, Northern, European, Southern) and one is steerable.
18 x 36 MHz transponders of planned frequency bands are used in the Russian beam exactly contouring the borders of the Russian Federation. This beam also features 4 x 54 MHz transponders utilizing standard frequency bands.
9-12 x 72 MHz transponders can operate in a wide Northern beam with its coverage zone over the visible part of Russia, the CIS countries, almost all of Europe and part of Middle East.
4 x 54 MHz transponders operate in the European beam, covering East and Central Europe, Middle East and Northern Africa.
8 x 54 MHz transponders operating in a wide Southern beam, covering the Sub-Saharan Africa.
Up to 3 x 72 MHz transponders can operate in the steerable beam providing a possibility of interbeam connection of the Southern beam with the Russian, European and Northern beams.
