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.

The Department of Transportation (DOT) submitted its “National Timing Resilience and Security Act: Roadmap to Implementation” report to Congress in mid-January. Following a competitive application process, demonstrations and review of 11 candidate technologies to back up GPS capabilities, the DOT concluded that “none of the systems can universally backup the positioning and navigations capabilities provided byGPS and its augmentations.” However, “all vendors demonstrated some PNT performance of value, but only one vendor, NextNav, demonstrated in all applicable use case scenarios.”

The SiriusXM satellite radio network now broadcasts GNSS corrections from Trimble’s RTX service. New cars sold in the contiguous U.S. and Canada equipped with SiriusXM’s Gen8 satellite chipset will be able to receive RTX GNSS corrections, without the need to access a cellular network, thus enabling high-accuracy positioning, a key component of autonomous on-road applications.
