Astra 3B is a television satellite operated by SES Astra. It will complement the Astra 3A satellite at the orbital position 23.5 ° East and replace the Astra 1E and 1G satellites, which are also positioned there. After Astra 3A has given up its services to him and has left the position 23.5 ° East, he is alone at 23.5 ° East.
Astra 3B was built by EADS Astrium and is based on the Eurostar E3000 satellite platform . It has 60 transponders in the Ku band and four transponders in the Ka band. 52 Ku-band transponders and all four Ka-band transponders should be active. The Astra 3B's engines use MMH as fuel and the MON 3 oxidizer . The start was planned for April 9, 2010, but had to be postponed three times before it could finally take place on May 21.
