Astra 3A is one of the Astra communications satellites owned and operated by SES, launched in 2002 to the Astra 23.5°E orbital slot providing digital television and radio for DTH and cable, multimedia and interactive services, corporate networks, and occasional and other business services to central Europe.
The satellite provides two broadcast beams, of horizontal and vertical polarisation, across two footprints that cover essentially the same areas of Europe – principally the countries of central Europe.
Astra 3A was launched to provide follow-on capacity to replace the DFS-Kopernikus 3 satellite and deliver additional capacity for the Benelux countries and central Europe, to create SES-Astra’s third major European satellite hotspot after Astra 19.2°E and Astra 28.2°E with access to channels at both positions using a single dish fitted with a monoblock Duo LNB.
TV signals can be received with a 50 cm dish across Germany, Austria, Switzerland, Belgium, the Netherlands, Luxembourg, the Czech Republic, most of Denmark, and in parts of France, Italy, Poland, Slovenia, and Slovakia. Reception is even possible as far afield as Scotland, Sweden and Serbia when a larger dish (around 110 cm) is used.
In addition to contribution feeds and individual TV channels, Astra 3A carried pay-TV networks including Kabel Deutschland (Germany), CanalDigitaal (The Netherlands), TV Vlaanderen (Belgium), CS Link (Slovakia and Czech Republic) and Skylink (Slovakia and Czech Republic). On February 1, 2012 Kabel Deutschland left Astra 3A.
