From ESA: “Galileo put to the test”

European Space Agency

Europe’s next pair of Galileo satellites have been the focus of a busy autumn at ESA’s technical centre in the Netherlands, continuing a full-scale campaign to ensure their readiness for space.

With the first four Galileos already in orbit, these new versions are the first two of a total 22 ‘Full Operational Capability’ satellites being built by OHB in Germany with a payload from Surrey Satellite Technology Ltd in the UK.

The second satellite joined its predecessor in mid-August at ESA’s European Space Research and Technology Centre in Noordwijk. This is the largest spacecraft testing site in Europe, with a full range of space simulation facilities under a single roof in cleanroom conditions. A wide range of tests have been performed on the two satellites.

The European Space Agency (ESA), established in 1975, is an intergovernmental organization dedicated to the exploration of space, currently with 19 member states. Headquartered in Paris, ESA has a staff of more than 2,000. ESA’s space flight program includes human spaceflight, mainly through the participation in the International Space Station program, the launch and operations of unmanned exploration missions to other planets and the Moon, Earth observation, science, telecommunication as well as maintaining a major spaceport, the Guiana Space Centre at Kourou, French Guiana, and designing launch vehicles. ESA science missions are based at ESTEC in Noordwijk, Netherlands, Earth Observation missions at ESRIN in Frascati, Italy, ESA Mission Control (ESOC) is in Darmstadt, Germany, the European Astronaut Centre (EAC) that trains astronauts for future missions is situated in Cologne, Germany, and the European Space Astronomy Centre is located in Villanueva de la Cañada, Spain.
