Contenido SES-Astra (Société Européenne des Satellites-Astra) is a Luxembourg-based company that owns and operates the Astra series of geostationary satellites b>, which transmit approximately 1100 digital television and radio channels via 176 transponders to 91 million homes throughout Europe.
The satellites
SES Astra operates with twelve satellites from three orbital locations, seven at 19.2°E, three at 28.2°E and two at 23.5°E. The company has three satellites under construction to replace the Astra 1 models in the near future. The Astra satellites work under the principle of co-location (several satellites in the same orbital position) which allows for increased flexibility and redundancy.

Notes
- 19.2°E is the most common orbital position for television and satellite radio in Germany and Central Europe.
- 1G is also used for satellite internet (with DVB modems) and the broadcast of television and radio channels.
