The Galileo Public Regulated Service (PRS) is a robust, encrypted navigation service for the European Union and partner countries’ government-authorised users. It is intended for security and defence applications. PRS goes significantly above and beyond the Galileo Open Service, providing authorised users with a better continuity of service when access to other navigation services may be degraded. It also increases the likelihood of continuous Signal-In-Space (SIS) availability in the presence of malicious interference.
These improved protection and resilience measures make Galileo PRS signals highly resistant to attacks, particularly in the form of spoofing and jamming.
Other Galileo services
EGNOS Data Access Service (EDAS) provides ground-based access to EGNOS data through the Internet in near real-time. With a controlled access system, EDAS allows users to connect to a variety of services which provide raw GPS, GLONASS, and EGNOS data, plus EGNOS augmentation messages.
EGNOS Open Service (OS) provides free and accessible use of EGNOS services to any user equipped with a GPS/SBAS-compatible receiver.
The EGNOS Safety of Life (SoL) assisted service for Maritime Users (ESMAS) is the first Satellite-based Augmentation System (SBAS) service tailored to maritime users.
The EGNOS Safety of Life (SoL) Service improves the accuracy and reliability of GPS, and soon, Galileo, and provides timely alerts when navigation performance degrades.
