Hispasat 1B



Hispasat 1B was a Spanish geostationary communications spacecraft launched by an Ariane 4 booster from the Kourou Space Center in French Guiana. It was launched 10 months after its sister satellite, Hispasat 1B. Based on the Eurostar spacecraft bus developed by British Aerospace and Matra Marconi, Hispasat was designed to support civil, military and government communications requirements through an array of multi-frequency transponders. With an on-orbit mass of 1.1 metric tons, the government owned satellite carried 15 active transponders: three X-band with one spare and 12 Ku-band (8 at 55 W, 4 at 110 W) with six spares. The Hispasat bus measured 1.7 m by 1.9 m by 2.1 m with a solar array span of 22 m and an initial capacity of 3.2 kW. The spacecraft design life was 10 years.
