Astra

SES-Astra (Société Européenne des Satellites-Astra) is a Luxembourg-based corporation which owns and operates the Astra series of geostationary satellite which transmit some 1100 analogue and digital television and radio channels via 176 transponders to 91 million households across Europe.

There are currently 13 Astra satellites in orbit, not all currently in service, located at the following positions in geosynchronous orbit:

• At 5.2 degrees east: Astra 1A.
• At 19.2 degrees east: Astra 1B, 1C, 1E, 1F, 1G, 1H, 2C.
• At 23.5 and 24.2 degrees east: Astra 1D, 3A.
• At 28.2 degrees east: Astra 2A, 2B, 2D.

Each satellite contains a large number of transponders, each of which can be directed to have a footprint covering different countries. The footprints of where each transponder can be received by a dish of 50-60 cm diameter is given below (note: "most" = covers more than 50% of a country, "part" = covers less than 50% of a country):
