Astra 23.5°E
Astra 23.5°E is a group of Astra communications satellites co-located at the 23.5° east position in the Clarke Belt owned and operated by SES based in Betzdorf, Luxembourg. 23.5° east is one of the major TV satellite positions serving Europe (the others being at 19.2° East, 13° East, 28.2° East, and 5° East).
The satellite currently occupying this position is the Astra 3B craft, which provide for services downlinking in the 10.70 GHz-12.70 GHz range of the Ku band and 21.40-22.00 GHz range of the Ka band across most of Central, Western and Eastern Europe and the Middle East.
A major reason for the usage of Astra 23.5°E as a source for direct-to-home (DTH) broadcasting is its proximity to Europe’s primary DTH position, Astra 19.2°E, allowing the use in target countries of a single small dish fitted with a monoblock Duo LNB to receive channels from both positions.
Astra 23.5°E is a major source of TV and radio channels and multimedia services for parts of Europe. While the satellite Astra 3B can reach most parts of the continent, this position is primarily used for channels broadcast to the countries of Northwestern, Central and Eastern Europe, in particular: Belgium, Bulgaria, Czech Republic, Germany, Hungary, Netherlands, and Slovakia.
