Astra 1M is one of five television satellites at 19.2 ° East of the Eurostar E3000 type of SES Global (formerly SES-Astra - Société Européenne des Satellites-Astra) based in Betzdorf in Luxembourg, the one for television reception in Europe and the Middle East is set. Astrium is the prime contractor and is responsible for the development and construction of the satellite as well as the delivery of the payload and the Eurostar E3000 platform.
SES Global planned to move this communications satellite to a geostationary position as early as May 2008 with a Proton M launcher . The launch was postponed to October 2008 due to technical problems with the rocket. On November 6, 2008 Astra 1M took off with a Proton-M / Bris-M and was maneuvered to its final position at 19.2 ° east longitude by mid-January 2009.

Since January 20, 2009, the satellite channels can be received in Europe (via 1M Europebeam) and in the Middle East (via 1M Widebeam) and will replace the channels on the Astra 1G satellite . The Astra 1G satellite was moved to 23.5 ° East in February 2009. Astra 1M has 36 transponders (after 5 years at least 32 functional transponders are expected) in the Ku band and three retractable reflector antennas.
Technical specifications
The satellite is based on the satellite bus euro E3000 . It has a takeoff mass of 5.3 tons and will still have an output power of 10 kW at the end of its service life. The span of the two solar collectors is 35 meters in operation. For orbit correction, the satellite has a main engine with 500 N thrust and 14 attitude control engines, each with 10 N thrust.
