Astra 1B



Astra 1B, a direct television satellite, was launched for Luxembourg by the European Space Agency on March 2, 1991, using an Ariane booster rocket. It provided TV programming to some 90 percent of the metropolitan and urban areas of Western Europe and the Canary Islands. Its communications payload consisted of 16 active 60-watt Ku-band transponders and six spares. Signals could be received on small 60-cm dishes. Colocated with Astra 1A above 19.2 degrees E, Astra 1B boosted system capability to 32 TV channels and radio braodcasts. It was built by GE Astro-Space for Societe Europeenne des Satellites (SES), Luxembourg. It was box-shaped, measuring 2.9 by 2.3 by 2.2 m. Solar arrays, supplying 3,700 W at end of life, spanned 24.4 m. It had a 10-year design life.
