Meridian 6

Meridian 6 (Меридиан-6) is a Russian military communications satellite, one of the Meridian series. It is designed to carry military communications traffic and is a replacement for the molniya satellites. In common with the earlier satellites these craft are in molniya orbits, a highly elliptical orbit named after the earlier satellites and giving good coverage of northern Russia.

Meridian
Meridian satellites are the replacement for older Soviet molniya satellites, and some authors think some functions of the parus satellites. They are built by ISS Reshetnev and may share some components with their GLONASS-M satellites. The first Meridian satellite was launched in 2006 and two of the six launched so far have failed - Meridian 2 due a problem with the Fregat upper stage and Meridian 5 due to a problem with the third stage motor.

The satellites are believed to have a pressurised bus and a three axis control system. They are manufactured by PO Polyot on behalf of ISS Reshetnev. They have the GRAU index 14F112.

Launch
Meridian was launched on 14 November 2012 from Plesetsk Cosmodrome launchpad 43/4 by a Soyuz-2.1a rocket with a Fregat upper stage. It was launched at 11:42 UTC and the satellite and upper stage separated from the rocket at 11:51 UTC. The satellite was then released from the upper stage into a molniya orbit at 14:00 UTC. It was given the international designator 2012-063A and the United States Space Command assigned it the Satellite Catalog Number 38995.

The launch was attended by newly appointed Russian defence minister Sergei Shoigu in his first visit to the troops since being appointed on 6 November 2012.
