Société Européenne des Satellites (SES) of Luxembourg ordered a Boeing satellite, ASTRA 2C, in August 1999. ASTRA 2C will be stationed at SES' second orbital position of 28.2 degrees East longitude. ASTRA 2C is a Boeing 601 HP model, the 8th 601 in SES' fleet and its 4th of the HP (High-Power) version. It was sucessfully launched from Baikonur, Kazakhstan on June 16, 2001.
ASTRA 2C will provide pan-European coverage. The satellite will have the flexibility to operate at SES' primary slot of 19.2 degree East longitude. ASTRA 2C, a body-stabilized spacecraft, will operate with 28 Ku-band transponders.
The Boeing-built ASTRA satellites are similar in appearance to other Boeing 601 models, with each having a cube-shaped body and two solar array wings oriented along its north-south axis and the antennas located on the east-west axis.
SES is the owner and operator of ASTRA, Europe's leading satellite system for direct-to-home reception, transmitting analog and digital TV and radio services as well as multimedia and Internet content to an audience of more than 80 million households in Europe. SES holds a strategic 34.13 percent participation in AsiaSat, Asia's premier satellite operator, providing broadcast and telecommunications services to 53 countries in the Asia/Pacific region. Through its strategic investments in AsiaSat, NSAB and Embratel, SES will be able to interconnect the European ASTRA and Sirius satellites with the Asian/Pacific AsiaSats and the Latin American Brasilsats to offer satellite broadband services spanning four continents. SES also has part ownership of Brasilsat (20%, since October 2000) and Nordic satellite Company (50 %, also since October 2000).
BSS is the world's leading manufacturer of commercial communications satellites, and a major provider of space systems, satellites and payloads for national defense, science and environmental applications.
