This article contains orbital elements but does not include an epoch, or date when those elements, which typically vary over time, were correct. Please help by adding the epoch for the current data, or changing the orbital elements to ones with a known epoch.
Meridian 6 (Russian: 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 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.
