Satellite positioning (GNSS, GPS etc.)

Creating and simulating satellite-based navigation systems

GNSS simulators from Rohde & Schwarz are able to generate signals from all operational satellite-based navigation systems, including GPS, Glonass, Galileo, BeiDou, SBAS and QZSS in the frequency bands L1, L2 and L5. Simulation capabilities include correct modelling of satellite orbits including orbit errors and perturbations as well as other typical error sources like ionospheric and tropospheric effects as well as satellite clock errors.

Ideal for testing automotive GNSS receivers

GNSS test solutions from R&S are the ideal tool for testing automotive GNSS receivers, providing a complete feature set to set up test scenarios for automotive applications. This includes

Simulation of a moving receiver with consideration of vehicle attitude
Realistic environment simulation with consideration of signal obscuration and multipath effects, including configurable scenarios for driving through urban canyons or tunnels and consideration of signal obscuration by the simulated vehicle itself
Real time streaming of external trajectory data to the GNSS simulator; by using this feature, the simulator can be operated in a hardware- or vehicle-in-the-loop environment (HiL/ViL).
Simulation of interference and coexistence scenarios to test the receiver’s resilience against typical GNSS threats including jamming and spoofing

Be compliant

GNSS simulation solutions from R&S allow to test automotive GNSS receivers and emergency call systems. R&S offers solutions for

Testing GNSS receivers against standards of the EU’s Radio Equipment Directive (RED)
Conformance and performance testing of eraGlonass modules
Conformance and performance testing of eCall modules

Benefits

Realistic: scenarios with consideration of typical GNSS error sources
Customizable: GNSS testing under controlled conditions
Repeatable: Ensure identical conditions for each test run
