Automated GNSS performance tests on eCall modules

February 12, 2018 // By Julien Happich
From April 1, 2018 onward, all newly registered cars and light trucks in the European Union must be equipped with the eCall automatic emergency system. Before eCall or ERA-GLONASS modules can be integrated into cars, they need to be certified.

The GNSS receiver integrated into the eCall module typically evaluates signals from GPS, Galileo and satellite-based augmentation systems (SBAS) to determine the vehicle position. In an emergency, the module automatically places a call to the nearest emergency call center and transmits vehicle position data and other information via a cellular link. To make sure the accuracy of the reported position as well as a number of other performance parameters are within certain limits, the built-in GNSS receiver has to be tested against the criteria defined in the EU2017/79, Annex VI and UNECE 2016/07specifications.

A new option for the R&S SMBV100A vector signal generator together with test automation software delivers standard-compliant, fully automated performance tests for the GNSS receiver integrated in the eCall module.

The R&S SMBV100A in combination with the new R&S SMBV-K361 option and the R&S CMWrun sequencer software combine well to fully automate GNSS performance tests on eCall modules in line with the EU2017/79, Annex VIand UNECE 2016/07 specifications. All test cases specified in these documents can be configured, scheduled and conducted automatically with this solution.
