Two years ago, Inside GNSS published a feature article describing some exciting new capabilities and business models making GNSS use a key contributor to deploying European Rail Traffic Management System (ERTMS) on local and regional lines. Today, the train control segment remains one of the most important components of the railway market. In the railway domain, this control segment also is one of the most important in terms of industrial and technological innovation, in particular in Europe with the development and the continuous improvement of the European Rail Traffic Management System/European Train Control System (ERTMS/ETCS) standards.

The EU’s Galileo program posted an official notice on 11 July advising users that Galileo service is degraded on all satellites until further notice.
By Inside GNSS Our source inside the European GNSS Agency (GSA), which is the EU agency responsible for Galileo services, has told us: “They are working on it. Teams from industry and the Agencies are working 24/7 to restore the Galileo services as soon as possible to their nominal levels. The current estimation is that the services should be restored within 48 hours. In any case, we expect the service to be again nominal before the end of the weekend [13-14 July 2019],” the source said.
