List of Ekspress satellites

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

Main article: Ekspress

Ekspress (Russian: Экспресс, literally Express) is a communication and broadcasting system developed and operated by Russian Satellite Communications Company (RSCC). It is the largest network of Russia and its slots cover an arc in geostationary orbit from 14.0° West to 145.0° 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[edit]

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