Meridian-M satellites carry three transponders operating in different frequency bands for a service life of 7 years. The rocket will fly in th e Soyuz 2.1a configuration with a Fregat-M upper stage.\n-\nThe Meridan-M communications satellites are built by ISS Reshetnev on a ~2 tonne pressur ized bus structure\, possibly based on the Uragan-M bus for the GLONASS co nstellation. The Meridian series is reported to be the replacement for all the Molniya-1T\, the Molniya-3 and Molniya-3K satellite series and possib ly also for the communication component of the Parus. Meridian-M is the hi ghly eccentric orbit (HEO) component of the Integrated Satellite Communica tions System (ISSS)\, working in conjunction with the geostationary Raduga -1M (Globus-M) satellites.
