ESA satnav receiver vans – driving between the busy heart of Rotterdam, quiet countryside, and the Agency’s ESTEC technical centre – have confirmed that Galileo signals now provide a first position fix more rapidly, while also offering improved robustness in challenging environments and streamlined access to time information.

The improvement comes from a new so-called improved ‘I/NAV’ navigation message, first demonstrated on the latest two Galileo satellites launched in December 2021 and entered into service last summer. ESA as Galileo’s System Design Authority has been contributing to the deployment of the improved ‘I/NAV’ navigation message starting from the design phase, the implementation at satellite and ground segment, the qualification of the implementation and the in-orbit testing.

Galileo’s service provider, the European Union Agency for the Space Programme, EUSPA has now upgraded all other Galileo FOC satellites in service so as to broadcast this enhanced navigation message.
