Galileo put to the test

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.
