Meridian 6 (Russian: Меридиан-6), also known as Meridian No.16L, 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 satellites are the replacement for older Soviet molniya satellites, and some authors think some functions of the parus satellites. It was constructed by ISS Reshetnev and is believed to be based on the Uragan-M satellite bus, which has also been used for GLONASS navigation 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.
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.
