Eurostar (satellite bus)
Eurostar is the name of a family of satellite buses from Airbus Defense and Space (formerly Astrium ). It is used in communication satellites in geosynchronous orbits . 84 satellites based on this bus had been ordered by June 2019.
Eurostar series satellites are designed for a wide variety of telecommunications applications, including cellular services , broadband internet and television.
development
Eurostar was jointly developed by Matra Marconi Space and British Aerospace beginning in the 1980s . The goal was to develop a satellite bus for satellites with a total mass of 1.8 to 2.5 t for the Ariane 4 launch vehicle and the space shuttle with PAM-D2 upper stage. The electrical output was 1300 to 2600 W. It was the first satellite bus based on a modular concept for digital control. Based on this, all satellite-specific parameters are anchored in the software, which allows adaptation to different mission profiles without changing hardware. The original structure and configuration has been improved over the years, allowing the payload capacity and performance to quadruple from 1987 to 1992. The requalification effort was minimal. The basic structure of the Eurostar satellites has not fundamentally changed in the Eurostar E1000 , E2000 , E2000 + and E3000 generations . The takeoff mass was increased to up to 6300 kg.
