Services

The Galileo system, once fully operational, will offer the following high-performance services worldwide:

Operational services:

• Open Service (OS): the OS enables free-of-charge navigation, positioning and timing services to European citizens and users worldwide. It is the service used by, for example, smartphones and vehicle navigation systems.
• High Accuracy Service (HAS): The free-of-charge, globally available high-accuracy positioning service is aimed at applications requiring higher performance than what is offered by the Galileo OS.
• Public Regulated Service (PRS): The Galileo PRS is an encrypted navigation service for government-authorised users and sensitive applications that require high continuity.
• Search and Rescue Service (SAR): The SAR/Galileo free-of-charge service contributes to lifesaving missions by locating beacon distress signals and forwarding data to the Search And Rescue Centre nearest to the location of the incident, supporting COSPAS-SARSAT MEOSAR.
• Open Service Navigation Message Authentication (OSNMA): Free-of-charge service that complements the OS by delivering authentication data, assuring users that the received Galileo navigation message comes from the system itself and has not been modified.

Services under development: 

• Signal Authentication Service (SAS): will enable an authenticated positioning free-of-charge service by complementing the OSNMA with E6-based ranging authentication capabilities targeting to support civil applications.
• Emergency Warning Satellite Service (EWSS): A free-of-charge service for national civil protection authorities to broadcast alerts directly to the population. The service contributes to enhanced risk management, and increases the resilience of society against natural or man-made threats.
• Timing Service (TS): A free of charge service that provides timing and synchronisation information, including monitoring of GST and UTC products.
