Precise GNSS receivers

Whether it is navigation with a smartphone, autonomous driving or in the smart city , the use of GNSS receivers (Global Navigation Satellite Systems) has become an indispensable part of our everyday lives. All applications have in common that they always need the optimal position and time information.

Fraunhofer IIS develops customer-specific receiver solutions for all available satellite navigation signals such as Galileo, GPS, GLONASS, BeiDou and SBAS in the multi-frequency range or optimizes existing systems. Basis for this is the GOOSE receiver development platform, ensuring optimal position and time information at all times.
