Sirius 2 is the first Aerospatiale Spacebus 3000-B satellite, with a redesigned propulsion system, built for NSAB (Nordiska Satellitaktiebolaget) of Sweden as a follow-on to Sirius 1 and Tele-X. It will be stationed at 5 deg E. NSAB will market half the transponders and GE Americom (later SES Americom) the rest. GE Americom called the satellite GE-1E (E for Europe). Mass is 2920 kg full, 1760 kg BOL, 1245 kg dry. Satellite is 2.3 x 3.4 x 3.5m with 29m solar panel span and 7 kW power.

In 2003 Sirius 2's pan-European beam was transferred to NSAB by SES Americom. By 1998 Sirius 2 was owned by SES Sirius, and was renamed Astra 5A. It was moved from 5E to 31.5E.
