GMV is currently developing the ground control segment for the in-orbit validation (IOV) system for Galileo Second Generation satellites (G2G), under a contract signed recently with the European Space Agency (ESA). The contract exceeds €200 million in value, making a total of more than €500 million in contracts signed by GMV for work on the Galileo program since 2018.

As of August, 2023, operational Galileo GNSS satellites, with some exceptions, have been updated and are now transmitting an improved I/NAV message. Users will see an enhancement in the Galileo E1 Open Service (OS) performance in terms of robustness and a significant reduction in time to first fix in challenging environments, with both unassisted and assisted GNSS. Backward compatibility is assured, with no impact on legacy receivers and low complexity implementation within OS receivers.

The European Agency for the Space Program (EUSPA) is moving forward with its rollout of the free Galileo high accuracy service (HAS). Speaking at the recent HAS Days event in Spain, EUSPA’s Carmen Aguilera said, “Galileo HAS is user driven, as is the case for all European space programs. Our goal is to make sure that the services we are delivering are tailored to meet the needs of the users and the industries that will employ them in their businesses.”
