The Rohde & Schwarz CMW500 is being used to test the ERA-GLONASS system.
The Certification Center Svyaz-Certificate in Russia is now using the R&S CMW500 to certify ERA-GLONASS systems in line with the TR CU 018/2011 technical guideline. The independent Russian test lab is currently the only test lab in Russia accredited to certify these systems. The R&S CMW500 is a wideband radio communication tester.
Equipped with the R&S CMW-KA095 application software, the R&S CMW500 meets all requirements for testing ERA-GLONASS systems and provides reliable, reproducible tests in line with the Russian GOST R 55530 specification, Rohde & Scwarz said. In addition, the R&S CMWrun sequencer software (R&S CMW-KT110) makes the test solution fully automated and user-friendly.

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.
Swiss u-blox introduces the surface-mount MAX-M5Q, a compact satellite positioning module that supports GPS and GLONASS, as well as Japanese QZSS satellite GNSS systems. High-performance GPS/GLONASS parallel operation is also supported to enhance positioning speed and accuracy.
Designed for use in rugged environments and wide temperature range, MAX-M5Q is intended for industrial machine-to-machine (M2M) applications as well as Russia’s ERA-GLONASS emergency call system. MAX-M5Q enhances positioning in poor GNSS satellite visibility conditions as well as in high latitude and polar regions, u-blox said.
“With parallel GPS/GLONASS operation, MAX-M5Q is able to track all 50 and more U.S. and Russian satellites to deliver incomparable speed, accuracy, and positional availability,” said Thomas Nigg, vice president of Product Marketing at u-blox, “Its compact size and high-reliability makes it an ideal positioning solution for mobile resource management and ERA-GLONASS emergency call applications.”
With dimensions of 9.7 x 10.1 x 2.5 mm, MAX-M5Q is the newest member of u-blox’ MAX GNSS LCC module series. Additional features include autonomous A-GPS that reduces warm start TTFF by as much as 90%, and an embedded data logger which can store location information to internal Flash memory for up to 16 hours at 15 second intervals.
