The Galileo Public Regulated Service (PRS) offers authorities and organizations with security tasks, operators of critical infrastructures as well as officially authorized users the possibility to securely determine time and place with its especially protected and encrypted satellite navigation signals (GNSS). Due to the high security requirements, Galileo PRS receivers are limited in their application compared to miniaturized mass-market receivers, especially due to their size and power consumption.
Fraunhofer IIS develops server-based Galileo PRS receiver technologies. Raw data of Galileo PRS signals are recorded in miniaturized and low-power terminals and sent to an especially protected server infrastructure (Cloud Computing), where the PRS signals are analyzed. Depending on the application, the secure and reliable PRS position and time solution can be sent back to the terminal or queried by a client. This enables further miniaturization and thus more diverse use of Galileo PRS for government-authorized applications.
