GNSS positioning on planet Earth
GNSS positioning with development of customized, high precision and secure GNSS receivers and GNSS antennas for specific applications that process signals from Galileo, GPS, GLONASS, BeiDou and SBAS on multiple frequency bands.

Server-based Galileo Public Regulated Service (PRS) Technologies

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.

Specific offer

  • Development of server-based Galileo PRS technologies with outsourced security module in an especially protected server infrastructure and processing concepts (Cloud Computing)
  • Support for new types of and innovative applications through proof-of-concept with sample & process (e.g. drone market, asset tracking, time signing and verification, etc.)
  • Use of Galileo PRS signal processing in our especially protected server infrastructure
  • Generation of a tamper-proof position and time solution without the use of conventional Galileo PRS receivers

Applications and projects

 

MPS

Manipulation of data in asset tracking impossible: The Mobile Galileo PRS Snapshot sensor provides tamper-proof position, time and sensor data by using the Galileo Public Regulated Service (PRS).

 

PRSauth

Galileo PRS and the outsourcing of crypto processing and large parts of the receiver (signal processing) to a secure server environment are used to realize tamper-proof, miniaturized and low-cost receivers.
