Galileo Public Regulated Service (PRS) Simulation

The functionality and performance of receiver and antenna technologies for Global Navigation Satellite Systems (GNSS) can be checked against specific requirements by simulation already in the concept phase or later. Simulation makes it possible to address specific applications and at the same time reduce development times. The prerequisite is a realistic simulation environment in which, as far as possible, all parameters such as satellite orbit, signal propagation or receiver environment are taken into account. But also the realistic modelling of the user's movement as well as the consideration of possible interfering signals play a decisive role here.

With the Galileo Public Regulated Service (PRS) signal generator, Fraunhofer IIS offers a simulation and test environment that is unique worldwide, but also a wide range of test and evaluation solutions with multi-GNSS simulators, record & replay systems, interferer detection and positioning stations as well as with further mobile measurement applications or a unique antenna measurement hall.

• Use of our multi-GNSS/INS/Galileo PRS signal generator environment
• Mobile use of multi-band and Galileo PRS suitable record & replay systems (Flexiband USB front-end)
• Combination of GNSS and Machine Learning technologies to protect against signal deception
• Development of and training on Galileo PRS signal simulators
• Test and evaluation with multi-GNSS simulators (Galileo, GPS, GLONASS, BeiDou, SBAS)
• Mobile multi-band record & replay systems, also for Galileo PRS
• Location-independent measurements and tests with our mobile measurement laboratory L.I.N.K. Mobil with high-end reference receiver incl. INS coupling for ground truth
• Array antenna as well as CRPA tests in the 3D GNSS wave-field synthesis 
• Antenna evaluation with commercial antennas and tests with measurement in our antenna measurement hall
