R&S simulator tests Russia’s emergency call system

January 10, 2017  - By 0 Comments

New cars for the Russian market must be equipped with the automatic ERA-GLONASS emergency call system.

For certification of these in-vehicle systems, both conformance and performance tests are mandatory, in line with the Russian GOST R 55534 specification.

The Rohde & Schwarz CMW500 is being used to test the ERA-GLONASS system.

The Rohde & Schwarz CMW500 is being used to test the ERA-GLONASS system.

For both types of tests, the Russian Certification Center Svyaz-Certificate uses standard-compliant test solutions from Rohde & Schwarz. Manufacturers and component suppliers can use the same test solution in pre-tests to speed up certification for their products.

The R&S SMBV100A was first used in the mandatory conformance test, with an R&S CMW500 wideband radio communication tester, GNSS simulator and the associated application software.

Now, for the newly required performance test, the center is using the GNSS simulator in the R&S SMBV100A vector signal generator.

Accuracy Requirements. During performance testing, it is verified whether the GNSS receiver of an ERA-GLONASS emergency call system fulfills the accuracy requirements of the specification.

In case of an emergency, the call system should not only correctly transmit position data according to a specified protocol to the public safety answering point, but position data must also be accurate so that the first responder can locate the accident vehicle quickly.

ERA-GLONASS module manufacturers and test houses can use the R&S SMBV100A during pre-tests to create reliable and reproducible conditions similar to those in official certification tests, according to Rohde & Schwarz, to minimize the risk of failing tests during certification.
