R&S GNSS simulator adds options for real-world scenarios

Rohde & Schwarz recently announced additional support for their R&S SMBV100A global navigation satellite system (GNSS) simulator. The new R&S SMBV-K101 option allows developers in the automotive and wireless communications industries to test GNSS receivers for specific effects such as obscuration and multi-path propagation.

The option allows for easy configuration by taking into account structures, such as buildings, tunnels and bridges, as well as reflections from concrete and glass surfaces that affect the GNSS signal, regardless of whether the receiver is stationary or in motion. If the GNSS receiver of a navigation instrument or smartphone is located inside a vehicle, the R&S SMBV-K102 option also takes such factors into account, simulating this obscuration and, if required, also the additional antenna pattern.

In addition to test scenarios for A-GPS, smartphone developers also have the Assisted Galileo (R&S SMBV-K67) and Assisted Glonass (R&S SMBV-K95) options. In many cases, navigation instruments handle signals of digital communications standards other than GNSS. Now, manufacturers of mobile phones and car radios with integrated GNSS receivers need just one signal generator to test multiple functionalities. The R&S 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 400Hz. 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 realtime for GPS with civilian C/A code and military P code as well as for Glonass and Galileo in different constellations. In just a few steps, users can define their own scenarios for testing their GNSS receivers under various conditions. The R&S SMBV100A is the only GNSS simulator on the market that does not require an external PC. As a result, it is easier to automate, and test setup is simple.

The new options for the GNSS simulator in the R&S SMBV100A are now available from Rohde & Schwarz.
