Part of the Ekspress series of geostationary communications satellites, it is owned and operated by the Russian State Company for Satellite Communications.[4] It provides digital television and radio broadcasting, telephone, video conferencing, data transmission and Internet services. The satellite is also used for mobile communications among between the Russian president and other government leaders. Express AM5 carries 40 Ku-band, 30 C-band, 12 Ka-band and two L-band transponders. The satellite is designed for a 15-year lifetime and will be positioned in geostationary orbit at 140 degrees east longitude, covering Russia's Far East, Southeast Asia and Australia. Such an orbit allows the spacecraft to remain in a fixed location in the sky for users on the ground.[5] References1. ^{{cite web|url=http://www.nasaspaceflight.com/2013/12/russian-proton-m-launches-ekspress-am5/|title=Russian Proton-M launches Ekspress-AM5|first=Chris|last=Bergin|date=26 December 2013|accessdate=27 December 2013}} {{Portal|Spaceflight}}{{Ekspress}}{{Orbital launches in 2013}}{{Russia-spacecraft-stub}}2. ^{{cite web|url=http://voiceofrussia.com/news/2013_12_26/Carrier-rocket-Proton-M-with-Express-AM5-spacecraft-to-be-launched-from-Baikonur-7502/|title=Carrier rocket Proton-M with Express-AM5 spacecraft to be launched from Baikonur|work=Voice of Russia|accessdate=27 December 2013}} 3. ^1 2 3 4 {{cite web|url=http://www.n2yo.com/satellite/?s=39487|title=EXPRESS-AM5 Satellite details 2013-077A NORAD 39487|publisher=N2YO|date=22 January 2015|accessdate=25 January 2015}} 4. ^{{cite web| url =http://en.itar-tass.com/russia/713096| title =Express-AM5 satellite delivered to final orbit| work =Itar Tass| accessdate = 27 December 2013}} 5. ^{{Cite web|url=https://www.n2yo.com/satellite/?s=39487|title=Technical details for satellite EXPRESS-AM5|website=N2YO.com - Real Time Satellite Tracking and Predictions|access-date=2018-06-29}} 4 : Ekspress satellites|Spacecraft launched in 2013|Satellites using the Ekspress bus|2013 in Russia |
