A: While GPS satellite faults have always been infrequent, they have become rarer in the past decade due to the maturity of the GPS constellation and its Operational Control Segment (OCS). Lessons learned from past GPS satellite failures have also aided the development of newer GNSS constellations such as the European Galileo.

As part of its climate change policy aimed at reducing emissions by 70% by 2030, the Danish Government is rapidly moving towards the introduction of a GNSS-based road user charging (RUC) scheme for heavy goods vehicles (HGV). The intention is to introduce the new system starting in 2025, which will replace Denmark’s participation in the Eurovignette scheme, which applies to HGV weighing 12 tons or more.

The prototype, consisting of a single Tx-Rx communication link, was tested in indoor-to-indoor, outdoor-to-outdoor and outdoor-to-indoor communication scenarios and in both static and dynamic conditions. The outdoor-to-indoor results indicate that, with further development, the Civilian and Assets Recovery System (CARS) is a promising navigation and positioning technology.
