The freely available signals of the existing global navigation satellite systems (GNSS) such as the American GPS or the Russian GLONASS are used for a wide range of applications to determine position and time. However, the freely available signals are unencrypted and thus unprotected. As a result, they can easily be interfered with, manipulated or even switched off in crisis situations. With the introduction of the world's first global navigation satellite system under civilian control, Galileo, it is now possible for officially authorized users to use the especially protected, encrypted signals of the Galileo Public Regulated Service (PRS).
Fraunhofer IIS offers Galileo PRS receiver technologies to (inter-) national authorities and organizations with security tasks, operators of critical infrastructures and authorized users, thus enabling the generation of secure and reliable position and time information through Galileo PRS.
