The Galileo HAS Global Navigation Satellite System (GNSS) is now operational and offers unprecedented positioning accuracy. 

Galileo is now the first GNSS providing free-of-charge, high accuracy, Precise Point Precisioning (PPP) corrections worldwide through the Galileo signal in space and via the Internet. 

Emerging technology such as UAVs and autonomous vehicles require stringent levels of accuracy for better navigation experience, safety and efficient traffic management. An increase in accuracy positioning will feed innovative applications in transportation, agriculture, surveying, entertainment, and many other existing sectors. Galileo HAS will become a pilar for applications needing accurate and reliable position information. This will include EU sectoral policies and national policies by EU Member States. “The new service has been made possible thanks to the outstanding cooperation and team commitment of all involved partners,” declared EUSPA Executive Director Rodrigo da Costa. 

The Galileo High Accuracy Service (HAS) is a new and enhanced service of the EU’s GNSS. It offers a typical accuracy below a few decimeters (<25cm horizontal) in nominal conditions of use (Galileo). The service is transmitted directly via the Galileo signal in space (E6-B) and through the Internet. Galileo has become the first constellation worldwide with the capability to provide a high-accuracy service globally and directly through the Signal in Space. 

This service is accessible to all users with a receiver able to process the HAS corrections broadcast in the E6-B signal via the internet. Precise corrections provided by the Galileo HAS allows users of the service to reduce errors associated with the orbit and clocks provided through the Galileo Open Service broadcast navigation messages and the GPS Standard Positioning Service navigation data. 

“With the Galileo HAS we are ready to unleash the full potential of new technologies like drones and bring autonomous driving closer to reality,” says Costa. “At EUSPA our role is to link space to user needs. With the launch of this new service, we met a clear market demand for accurate, robust, and reliable navigation.”
