Join the Galileo HAS Full-Service testing campaign and contribute to the future evolution of Europe’s High Accuracy Service.

Combining OSNMA and the new Signal Authentication Service (SAS), the test proved resilience against spoofing, including during Jammertest in Norway, marking a major step towards more trusted and secure satellite navigation.

The Galileo Open Service (OS), the High Accuracy Service (HAS), the Open Service Navigation Message Authentication (OSNMA) and the Search and Rescue (SAR) Service Performance Reports for Q2 2026 have been published. 

Exploring Galileo services and their role in maritime applications 

Galileo SAS will complement OSNMA providing civilian users with authentication at ranging level for the Galileo E6-C signal component.

Oscilloquartz has integrated Galileo’s OSNMA authentication into its timing and synchronisation platforms, using u-blox GNSS technology, bringing a new level of trust and resilience to GNSS-based synchronisation for critical infrastructure.

July 2026 marks one year since the initial service for Galileo’s Open Service Navigation Message Authentication (OSNMA) has been declared operational, a milestone in the continued evolution of Galileo services for users worldwide.

Following the launch of Galileo satellites GSAT0233 and GSAT0234 in December 2025, the Galileo Satellite Metadata has been updated to include these new spacecrafts. The update provides essential information for high-precision GNSS applications, supporting accurate orbit determination and Precise Point Positioning. 

An in-depth look at Galileo’s High Accuracy Service (HAS) and Open Service Navigation Message Authentication (OSNMA) Service, covering performance, receiver technologies and practical implementation.
