Simulating Automatic Obscuration and Multipath for Realistic GNSS Receiver Testing

The R&S SMBV100A is both, a versatile general-purpose vector signal generator and a powerful GNSS signal simulator. It can simulate up to 24 satellites in realtime for testing GNSS receivers flexibly, reliably, and cost-efficiently. The R&S SMBV100A supports receiver testing under realistic conditions by offering features such as obstruction simulation and automatic multipath generation. Out of a multitude of possible test scenarios - with predefined or user specific settings - this application note presents some examples to give an impression of the instrument's capabilities.
