The R&S SMBV100A vector signal generator can generate Galileo, GPS, and GLONASS signals for up to 24 satellites in real time. With the SMBV-K107 option, the simulator covers the BeiDou standard as well. The 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 multipath propagation. 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, the additional antenna pattern. In addition to test scenarios for A-GPS, smartphone developers have the Assisted Galileo (R&S SMBV-K67) and Assisted GLONASS (R&S SMBV-K95) options at their disposal. Contact Rohde & Schwarz to learn more. For more products ready for Galileo, see our Galileo Product Showcase.
