2021/04/08 Rohde & Schwarz adds ERA GLONASS to its reliable test solution for in vehicle emergency call systems. Photo: Rohde & Schwarz Effective January 1, 2015, all new car models introduced to the Russian market must be equipped with the automatic ERA-GLONASS emergency call system. Rohde & Schwarz now offers a standard compliant test solution for manufacturers and suppliers of these in-vehicle systems. Rohde & Schwarz is demonstrating its ERA-GLONASS test setup at Mobile World Congress, being held this week in Barcelona, Spain. The test setup consists of the R&S CMW500 wideband radio communication tester and R&S SMBV100A vector signal generator as a GNSS simulator. This setup allows manufacturers and suppliers of automatic in-vehicle systems (IVS) to perform reliable and reproducible pre-conformance tests on their ERA-GLONASS modules in the lab. In the Russian Federation, ERA-GLONASS works much like the European Union’s eCall system. When an accident occurs, the IVS connects with a public safety answering point (PSAP) via the local wireless communications network and transmits a standardized minimum set of data (MSD). In addition to GLONASS or GPS coordinates, the MSD also contains data with information about the accident vehicle as specified in ERA-GLONASS. If no voice connection can be made or if data cannot be transferred via the voice channel, the MSD is sent to the PSAP via SMS. This fallback option is a special ERA-GLONASS feature. The Russian system is also certified for 2G and WCDMA networks. Rohde & Schwarz developed its R&S CMW-KA095 application software to meet ERA-GLONASS requirements in line with Russia’s GOST specification. Based on the R&S CMW-KA094 eCall software, the R&S CMW-KA095 simulates a PSAP and controls the R&S CMW500 emulating a wireless communications network in the lab. The software also controls the GNSS simulator that supplies the coordinates required for vehicle localization. With this solution, users can verify whether their IVS modem is able to successfully initiate an emergency call, transmit the correct MSD and establish a voice connection with a PSAP. The results are interpreted in line with the GOST specification. The ERA-GLONASS SMS protocol has also been integrated into the test solution, making it possible to test the SMS functionality of the IVS modem when no voice connection is available. The test solution is fully automated because of the R&S CMWrun sequencer software. The R&S CMW-KT110 eCall/ERA-GLONASS test package provides a user-friendly, automated functional test in line with GOST55330, enabling users to verify the operability of an entire system in the lab and document it in a report.
