In January 2009 ordered the Yamal-300K communications satellite from ISS Reshetnev as a replacement for the much delayed and cancelled Yamal 301 and Yamal 302 satellites. The satellite will be based on the Ekspress-1000NTA bus and was planned to be launched in 2010.

The Yamal-300K satellite was launched to the 90° East orbital slot, where it works together with the Yamal-201 satellite.

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.

Yamal-300K was placed into orbit by a Proton-M Briz-M launch vehicle together with the Luch 5B satellite in 2012.

The main applications for C-band capacity will be traditional satellite services:

  • TV distribution,
  • Services for corporative networks VSAT, rural area networks (telephony, data transmission, Internet access),
  • Internet access (DVB-S),
  • Big communication flows transmission.
