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.

Galileo Public Regulated Service (PRS) Simulation and GNSS Test Solutions

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.
