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.
