SES Sirius

SES Sirius, formerly called Nordic Satellite AB (NSAB) was the owner and operator of the two Sirius satellites, which provide the Nordic countries and the Baltic states, with TV, radio, data and communications solutions. The company is today entirely owned and controlled by SES and has no independent existence.

The 2004 SES Annual Report states that 16.4 million homes received broadcast and broadband services from the Sirius system, 1.5 million from the satellites directly and another 14.9 million from cable networks distributing content via Sirius.

In 1982 the governments of Sweden and Norway formed NSAB as part of a wide ranging partnership for the purpose of "telecommunication satellite cooperation". In 1989 the two governments agreed to end their partnership, the Swedish government assumed full ownership with the acquisition of Norway's 15% share.

On April 2, 1989 NSAB's first satellite, the Aérospatiale built Tele-X, was launched on an Ariane 2 rocket from French Guiana. The Swedish Space Corporation (SSC) was contracted to operate the TELE-X system and in 1993 the company acquired the Swedish government's shares, becoming the sole owner.

In late 1993 NSAB acquired Marco Polo 1, a Hughes 376 geostationary communications satellite, from British Sky Broadcasting. Marco Polo 1 was built for and operated by British Satellite Broadcasting. However following that company's collapse it merged with Sky Television to form BSkyB. In this "merger" Sky was the dominant force and their system of transponder lease from SES' Astra satellites was maintained. Marco Polo 1 (and its sister satellite) were gradually withdrawn from service.

In February 1994 Teracom acquired a 50% share of NSAB. The same month Marco Polo 1 re-entered service as Sirius 1 at 5°E. In July 1994 NSAB agreed the purchase of Sirius 2 from Aérospatiale (later Alcatel Space). The satellite was successfully launched on November 12, 1997 by Ariane 4 rocket. Shortly after launch SES signed a lease agreement for all transponders on the satellite.
