Ekspress (satellite constellation)

This article is about the satellite constellation. For the satellite bus, see Ekspress (satellite bus).

Ekspress (Russian: Экспресс, literally Express) is a communication and broadcasting system developed and operated by RSCC. It is the largest network of Russia and its slots covers an arc in geostationary orbit from 14° West to 145° East. This allows it to cover the whole territory of Russia, the CIS, Europe, the Middle East, Africa, the Asia Pacific region, North and South America, and Australia. [1] The only other Russian civilian satellite operator is Gazprom Space Systems with its Yamal constellation.[2]

Ekspress Satellite Series

While the Ekspress constellation started with a single model, during the years it has used many supplier and many models.[3][4]
