The Yamal-402 geostationary communications satellite was launched on December 8, 2012 by Gazprom Space Systems to provide Ku-band satellite communications services from 55°E orbital slot. It has 46 transponders across multiple beams with transmission power of 150W and accuracy of 0.1 degrees for station keeping and satellite orientation. The satellite provides coverage of Russia, Europe, and northern regions with various transponder bandwidths and polarization configurations.
