ESA today signed a contract to build a further eight Galileo satellites, alongside other agreements to modify Europe’s Ariane 5 launcher to carry four navigation satellites at a time.

The first Galileo satellites are already in orbit, with more on the way. Today ESA’s Director General and the UK’s Universities and Science Minister attended the grand opening of the facility where navigation payloads for the next batch of Galileo satellites are being built.

Programme managers and technical experts overseeing four of the world’s regional satellite navigation augmentation systems met this week, with ESA coordinating the participation of stakeholders in Europe’s own EGNOS system.
