任务简介
Meridian系列通信卫星据报道将取代所有Molniya-1T、Molniya-3和Molniya-3K卫星系列，可能还包括Parus的通信组件。它们被发射到高椭圆Molniya轨道。 Meridian是综合卫星通信系统（ISSS）的高椭圆轨道（HEO）组成部分，与地球静止轨道的Raduga-1M（Globus-M）卫星协同工作。据称其总线结构是加压的，可能基于Uragan-M总线。Meridian卫星携带三个工作在不同频段的转发器。
原文
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. Meridian is the highly eccentric orbit (HEO) component of the Integrated Satellite Communications System (ISSS), where they work in conjunction with the geostationary Raduga-1M (Globus-M) satellites. The bus structure is reportedly pressurized, possibly based on the Uragan-M bus. Meridian satellites carry three transponders operating in different frequency bands.
