R&S adds simulated satellite system to vector signal generator

1 min read

A new option on the SMBV100A vector signal generator from Rohde & Schwarz is a global navigation satellite system (GNSS) simulator aimed at developers of satellite-based navigation instruments.

The new SMBV-K101 option allows developers 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, and this option makes it easy to configure these kinds of scenarios. If the GNSS receiver of a navigation instrument or smartphone is located inside a vehicle, testing must also take into account the obscuring effect of the vehicle's metal body. The R&S SMBV-K102 option can simulate 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 at their disposal. 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. Unusually the R&S SMBV100A does not require an external PC make tests easier to set up and automate.
