Test drive illuminates need to protect GNSS with proactive cybersecurity strategies
Tesla Model S and Model 3, electric cars built for speed and safety, are vulnerable to cyberattacks aimed at their navigation systems, according to recent research from Regulus Cyber. During a test drive using Tesla’s Navigate on Autopilot feature, a staged attack caused the car to suddenly slow down and unexpectedly veer off the main road.

With the launch of the first next-generation GPS III satellite, GPS III Space Vehicle 01 (GPS III SV01), on December 23, 2018, the Global Positioning System (GPS) took a major step in modernizing technology and capability. The U.S. Air Force has continually improved GPS since the launch of the first GPS Block I satellite in 1978, and this ongoing modernization has provided new signals, greater accuracy, and increased robustness for civil and military users. After the first 10 GPS III satellites are launched over the next few years, up to 22 GPS III Follow-on (GPS IIIF) satellites will provide yet another step increase in GPS capabilities.

An increasing number of applications require accurate, reliable, and traceable signals for time and synchronization. Key fields of application include banking and finance, telecom networks and electricity grids. GMV’s WANTime is a new time service for the city of Madrid, Spain, distributed using the White-Rabbit network protocol over optical fiber. A pilot customer of the service is currently the Madrid Stock Exchange (Bolsa de Madrid), connected to GMV’s datacenter by a network link of around 50 kilometers.
