Astra 5B is a commercial communications satellite owned by the Dutch SES World Skies . It replaces Astra 1G .
It was placed in geostationary orbit on March 22, 2014 at 22:04 UTC with an Ariane 5 ECA launcher from the Kourou rocket launch site (together with Amazonas 4A ) .
The five-meter satellite is equipped with 40 Ku-band - and 6 Ka-band - transponders equipped and provided for since 2 June 2014 the position 31.5 degrees East, Eastern Europe and Russia with television programs. It also carries an L-band payload of the European Geostationary Navigation Overlay Service (EGNOS), which is used to increase the accuracy of navigation signals from the GPS , GloNaSS and Galileo systems . It was based on the satellite bus euro E3000 (now Airbus Defense and Space) built by Astrium and has a design life of 15 years. Astrium was awarded the contract to build the four telecommunications satellites Astra 2E , Astra 2F , Astra 2G and Astra 5B in November 2009. These were launched gradually between 2010 and 2014.
reception
The satellite has a wide and a high-power footprint in the Ku band. In Germany only the latter can be received without great effort. It is noticeably stronger than the Astra 1G's west footprint. The wide footprint can be received in East Germany with moderate effort. Compared to the east footprint, the reception is also significantly better here. Since some programs switched from the west to the wide footprint when the Astra 5B went into operation, they can only be received in Germany with considerably greater effort. The completely encrypted transponders from the Georgian provider Magti-TV, on the other hand, switched from the east to the high-power footprint and can therefore, with a subscription, also be received in Germany.
