The Lunar GNSS Receiver Experiment (LuGRE) will demonstrate GNSS-based spacecraft navigation in transit to the Moon and on the lunar surface. This will open the door to operational use of existing Earth-based GNSS signals for real-time onboard positioning, navigation, and timing (PNT) around the Moon, increasing mission capability while reducing reliance on ground networks for PNT.

Europe’s Galileo navigation system has taken a significant leap forward with the completion of a major upgrade to its Galileo Ground Segment. As one of the most complex ground segments ever developed in Europe, the challenge lay in seamlessly upgrading a system that serves more than four billion users globally—without disrupting service.
