Belgium launches its first Smart Highway test environment where Septentrio GPS/GNSS receivers are integrated into vehicles and infrastructure to provide dependable, high-accuracy positioning and to aid sensor fusion in driverless navigation and truck platooning.
Roadside units along the highway will feature GNSS receivers acting as reference stations, sending out continuous positioning corrections. Onboard GNSS units will use these corrections together with built-in quality indicators to calculate trustworthy, sub-decimeter positioning. They will also provide precise timing for syncing the multitude of sensors onboard these “smart vehicles”.
The Advanced Interference Mitigation (AIM+) technology shields Septentrio receivers from interference. On a highway, an increasing number of trucks are equipped with illegal jamming devices to avoid road tolling. These jamming devices can interfere with GPS signals used by other vehicles and infrastructure.
Smart Highway is a project of the Flemish government which is coordinated by imec, a world-renowned research and innovation hub of nano-electronics and digital technology. Septentrio, Toyota, Ericsson and Telenet are contributing industry partners for the project, while UAntwerpen, UGent, among others are research partners. On the European level the CONCORDA project supports research and development of automated vehicle technology and infrastructure in Germany, Spain, France, Netherlands and Belgium.
