The European Space Agency officially announced testing of Galileo’s Open Service Navigation Message Authentication (OSNMA) in its signal-in-space, allowing the first OSNMA-protected position fix to be successfully computed. This is the first-ever transmission of authentication features in open signals of a GNSS.

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.
