Sund & Bælt tests GNSS technology

Future technology for charging motorists for using toll roads, bridges and tunnels will increasingly be based on satellite systems – Global Navigation Satellite System (GNSS) – such as the American GPS system, and the forthcoming, shared European system Galileo. Satellite systems can detect a vehicle’s position without the vehicle having to go through a toll station.

In order to ensure that motorists in Europe can pass all toll stations in each country in future, there is an EU requirement in the pipeline that facilities should be able to handle both the current microwave technology, such as BroBizz, as well as satellite-based technology.

As a result, Sund & Bælt has chosen to trial a new payment system that can replace or supplement the existing BroBizz at its own facilities. The trial is expected to run for two to three years, and preparations for it have just begun.

The trial should help to:


  • Prepare the Danish payment system to meet the EU´s requirements
  • Identify problems with data capture and control through the use of the satellite system
  • Analyse costs of charging via a satellite-based system


The trial will naturally include journeys across the Storebælt and Øresund fixed links, and there will be a focus on payment solutions at future fixed links, including the tunnel under the Fehmarnbelt and the potential harbour tunnel in Copenhagen.

It is also clear, however, that Sund & Bælt’s trial of a satellite-based payment system is also interesting from a broader perspective. It will provide useful information on the choice of technology, if at some point it turns out that there is political interest in the introduction of road pricing in Denmark.

This is why the study also seeks to ensure that the knowledge accumulated through the Sund & Bælt GNSS trial is made available to researchers and relevant stakeholders.
