Emergency Road Assistance (ERA-GLONASS) is a service provided in the Russian Federation with the goal of reducing response times for accidents or other emergencies on the roadways. This white paper briefly describes the technology behind ERA-GLONASS and presents conformance tests for ERAGLONASS using the R&S CMW500 RF tester and the R&S SMBV100A vector signal generator. A Test software for ERA-GLONASS makes it quick and easy to perform these tests with the GSM or WCDMA wireless communications standard. It also shows a test solution for GNSS performance tests for ERAGLONASS using the R&S SMBV100A vector signal generator and the option R&S SMBV-K360 together with CMWrun.
