Services
Galileo offers the following high-performance services worldwide:
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, 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. EUSPA actively contributes to the development of all areas of PRS user segment to continuously respond to user needs, and supports a wide and secure use of PRS in compliance with the PRS Decision 1104/2011.
PRS is similar to Galileo’s Open and Commercial GNSS services, but with some important differences:
- PRS will ensure better continuity of service to authorised users when access to other navigation services may be degraded (resilience).
- In cases of malicious interference, PRS increases the likelihood of the continuous availability of the Signal-in-Space (robustness).
Search and Rescue Service (SAR)
The Galileo SAR service contributes to lifesaving missions by swiftly relaying radio beacon distress signals to relevant SAR crews through dedicated payloads on board Galileo satellites, which are supported by three ground stations strategically deployed across Europe.
New services are under development:
Open Service Navigation Message Authentication (OSNMA)
Free access 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.
OSNMA is authenticating data for geolocation information from the Open Service through the Navigation Message (I/NAV) broadcast on the E1-B signal component. This is realised by transmitting authentication-specific data in previously reserved fields of the E1 I/NAV message. By using these fields, OSNMA does not introduce any overhead to the system, thus the OS navigation performance remains untouched.
Signal Authentication Service (SAS)
It will enable an authenticated positioning service by complementing the OSNMA with E6-based ranging authentication capabilities targeting to support civil applications.
Galileo Emergency Warning Satellite Service (EWSS)
Swiftly broadcasts alerts globally, allowing national civil protection authorities to directly transmit to smartphones (or any Galileo-enabled devices) for enhanced emergency response and resilient risk management.
Timing Service (TS)
A free-of-charge service that provides timing and synchronisation information, including monitoring of GST and UTC products.
