Rohde & Schwarz GNSS simulator

The global navigation satellite system (GNSS) simulator runs on the R&S SMBV100A vector signal generator. The simulator is suitable for developers who have to perform extensive tests on the receivers and components used in satellite-based navigation systems.

The R&S SMBV-K101 option allows developers in the automotive and wireless communications industries, for example, to test GNSS receivers for specific effects such as obscuration and multipath propagation. Buildings, tunnels and bridges as well as reflections from concrete and glass surfaces affect the GNSS signal, regardless of whether the receiver is stationary or in motion. New options expand the range of functions of its GNSS simulator by adding a series of realistic scenarios.

In addition to test scenarios for A-GPS, the simulator also features the Assisted Galileo (R&S SMBV-K67) and Assisted Glonass (R&S SMBV-K95) options.

The SMBV100A can also be used to perform interference tests on the DUT. Users in the aerospace and defence industry can use the R&S SMBV-K103 option to simulate the relative position of a flying object as well as its rotation at a rotation rate of up to 400 Hz. This allows developers to perform lab tests to determine how a flying object’s different positions, the ground reflection of GNSS signals and rotary movements affect reception quality.

The GNSS simulator in the R&S SMBV100A uses up to 24 satellites to generate signals in real time for GPS with civilian C/A code and military P code as well as for Glonass and Galileo in different constellations. The simulator does not require an external PC.
