In a demonstration of new services that NextGen TV can offer, BitPath, CAST.ERA and ONE Media publicly trialed “Enhanced GPS” broadcasts that could provide a tool for autonomous vehicle navigation and other applications.
By Inside GNSS The UK Chair of the Parliamentary Space Committee David Morris reportedly sees a path back into Galileo participation for his country, thanks to a major investment from Europe into the OneWeb system, which the UK controls.

For autonomous transport to become a reality, its operations must be at least as safe as existing ones. The European Commission’s Directorate-General for Defence Industry and Space (DG-DEFIS) has awarded mission evolution studies to assess how the future evolution of European GNSS (EGNSS) could be beneficial for innovative and demanding autonomous applications.

A new approach to achieving the safety needed for levels 3 and higher of autonomy builds on a thorough mathematical framework to support safety analysis, while delivering very tight position bounds.
On Memorial Day, just prior to the running of the legendary Indy 500 race, a new speedway star came out to shine. A driverless racecar, no less, aiming for track speeds above 120 mph with no human hands on the wheel.

A novel method to track Galileo E5 AltBOC signal phase adjusts and then combines the correlation results of the upper sideband and lower sideband signal to form a double-sideband correlation result, which is equivalent to AltBOC wideband receiving to some extent. Thus, a Galileo E5 wideband receiver can be achieved with only minor modification to a traditional GNSS single-sideband receiver. The method can be further applied to other binary offset carrier (BOC) signals.
