Meridian (14F112)

Meridian [NPO PM]

The Meridian series of communications satellites is reported to be the replacement for all the Molniya-1T, the Molniya-3 and Molniya-3K satellite series and possibly also for the communication component of the Parus. They are launched into highly eccentric Molniya-orbits.

The bus structure is reportedly pressurised, possibly based on the Uragan-M bus.

The first two satellites were launched on Soyuz-2-1a Fregat boosters, afterwards the improved Soyuz-2-1a Fregat-M took over. The fifth satellite was an exception, which used a Soyuz-2-1b Fregat-M booster inherited from another program. Launchsite was the Plesetsk cosmodrome.

The second launch reached only a 290 km × 36460 km × 62.8 orbit, indicating a Fregat failure during the end of the second burn, with the third burn not taking place. The fifth launch failed to reach orbit.
