Ekspress AT1 (Russian: Экспресс АT1) is a Russian communications satellite which was launched in March 2014. Part of the Ekspress series of geostationary communications satellites, it is owned and operated by the Russian State Company for Satellite Communications. It is based on the Ekspress-1000N satellite bus manufactured by JSC Information Satellite Systems. Its mass at launch is 1672 kg, and the power allocated to the payload is about 5600 watts. The satellite carries 32 Ku-band transponders, providing satellite TV to western and central Russia, as well as western and central Siberia, and almost all of Kazakhstan. The planned service life of the satellite is at least 15 years.^[2]^[3] It was launched in the framework of Russian Federal Space Program for 2006-2015, approved by the Government Decree №635 signed on 22 October 2005 by Prime Minister Mikhail Fradkov.
