One of the most appealing features of Galileo that GPS does not have is the signal-embedded integrity, which enables the system to inform users about the possible failure of the system. Thanks to this provision, the possibility of using GNSS in a safety-critical application (i.e. safety of life, SoL) can be envisaged for both EGNOS and Galileo. The receivers used for safety-critical application share some common specifications and are generally classified under the term ‘safety-of-life receivers’. The main characteristics of these types of receivers are their robustness and their capacity to identify failures coming from the constellations, from the signal in space, from the environment and from the receiver itself. Safety-of-life receivers are also subjected to a large quantity of specifications, resulting in a rigorous certification process.
The activities within the project are aimed to reach four main objectives:
- carry out thorough technological research oriented to identifying the technologies needed for SoL receivers;
- develop common structures which can be shared among the different application-oriented receivers;
- develop three basic SoL receivers prototypes for the three different application – aviation, maritime and rail;
- develop tools to assist in the development phase – two Galileo signal simulators will be developed.
The programme can be considered as a natural continuation of the GARDA programme. Core technology investigation and implementation will evolve, targeted at the SoL application of the GARDA core technologies.
