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 GALILEO Open Service results from a combination of open signals, free of user charge, and provides position and timing performance competitive with other GNSS systems.
Purpose
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:[2]
- GALILEO Open Service (OS) results from a combination of open signals, free of user charge, and provides position and timing performance competitive with other GNSS systems;
During the Initial Operational Capability (IOC) phase, the GALILEO open service, the search and rescue service and the PRS will be provided. At this stage, however, accuracy and availability will not yet have reached their optimum levels.[3]
