Description:

• YAMAL 300K will broadcast television and high-speed Internet service across Russia and neighboring regions for Gazprom Space Systems, a Moscow-based subsidiary of Gazprom, the Russian oil and gas producer. The 3,615-pound (1,640-kg) satellite carries eight C-band and 18 Ku-band transponders to Russia and nearby countries from an operating position at 90 degrees east longitude.
• The satellite is fitted with a combined payload including eight active 72 MHz transponders in C-band and eighteen active 72 MHz transponders in Ku-band.

Mission details:

• Russia's Proton orbited a pair of communications satellites on Nov 2, 2012 both built by ISS Reshetnev. Luch-5B uses an Ekspress-1000A bus and is the second of a pair of data relay satellites and will provide communications support to the Station. Yamal-300K is an Ekspress-1000HTA with C and Ku band payload for Gazprom Space Systems, part of the massive Russian Gazprom energy company.
• The Briz-M upper stage reached a 388 x 35735 km x 48.7 deg transfer orbit and ejected the DTB drop tank, which is being tracked. Khrunichev reported that the stage then made a circularization burn and relesed the satellites in near-synchronous orbit.
  On Nov 17, over two weeks later, the US appears only to be tracking the drop tank and not the payloads.
• As of Dec 8, 2012 Yamal-300K is on station at 90.8E while Luch-5B is still drifting west over 13W.
