The GALILEO System will be an independent, global, European-controlled, satellite-based navigation system and will provide a number of guaranteed services to users equipped with Galileo-compatible receivers. The definition of the GALILEO Services is based on a comprehensive review of user needs and market analysis. The Galileo mission and services have been elaborated during the initial definition phase in consultation with user communities and the Member States.
Introduction
There will be some services provided autonomously by Galileo and other services resulting from the combined use of Galileo and other systems. This leads to the classification of the Galileo services into four categories:[1]
- GALILEO satellite-only services: These services will be provided worldwide and independently from other systems by combining the signals broadcast by the Galileo satellites. There is a wide range of possible applications with different operational requirements that have been grouped around the following five reference services:
- GALILEO locally assisted services: The Galileo satellite-only services can be enhanced on a local basis through a combination of local elements. The result will be the provision of local services.
- EGNOS services: EGNOS will provide over Europe an augmentation to GPS and GLONASS services. This service will allow for early experience in development of Galileo-like applications. The EGNOS services will be combined with the Galileo satellite-only services. This will allow higher performance levels to be met by using different sources of integrity and navigation information.
- Galileo combined services: All the above-mentioned services will be combined with services provided by other navigation or communication systems. This possibility will improve the GNSS services availability at user level and open the door to a wide range of applications. The result will be the provision of combined services.

GALILEO Services
The following Galileo satellite-only services will be provided worldwide and independently from other systems by combining Galileo signals-in-space:[4]
- Open Service (OS): With positioning accurate to one metre, the freely accessible Open Service targets the mass market and is intended for motor vehicle navigation and location-based mobile telephone services. Free to the user, it provides positioning and synchronization information intended for high-volume satellite radio navigation applications;
- Safety-of-Life Service (SoL): The Safety of Life service will automatically inform users within seconds of a failure of any satellite or similar problem affecting performance. This service will be made available for safety-critical applications such as running trains, guiding cars, navigation and aviation. This service also fulfils the requirements of certain sectors for continuity, availability and accuracy and includes an integrity function alerting the user of any failure in the system;
- Commercial Service (CS): Encrypted and accurate to the nearest centimetre, the Commercial Service allows for development of applications for professional or commercial use owing to improved performance and data with greater added value than that obtained through the open service;
- Public Regulated Service (PRS): The Public Regulated Service is restricted to government-authorised users, for sensitive applications which require a high level of service continuity. It will be encrypted and designed to be more robust, with anti-jamming mechanisms and reliable problem detection. This service is intended for security and strategic infrastructure (e.g. energy, telecommunications and finance);
- Search and Rescue Service (SAR): Galileo's worldwide search and rescue service will help to forward distress signals to a rescue coordination centre by detecting emergency signals transmitted by beacons and relaying messages to them.
The Galileo performances are different for each service. See the article Galileo Performances for further information.
