TUD COST Action TU1302
Satellite Positioning Performance Assessment for Road Transport



Global Navigation Satellite Systems (GNSS) have a very high potential in the development of Intelligent Transport Systems (ITS), Personal Mobility and associated services. This has been widely demonstrated through the use of GPS in supporting the provision of ITS services such as personal navigation, fleet management, cooperative traffic management and more recently: Road User Charging (RUC), Pay-As-You-Drive insurance, emergency call (eCall), tracking and tracing of dangerous goods, Advanced Driver Assistance Systems (ADAS), etc.

This is expected to grow significantly due to improvements in positioning performance, with positive impacts such as: increasing road network level of service or quality given a certain capacity of the infrastructure; improving traffic and travel efficiency as well as safety and security; reducing congestion and optimizing fuel consumption.

Due to the challenge of estimating properly the GNSS positioning accuracy and proving integrity messages to the users, the road transport sector (motorised modes, but also “soft” modes like pedestrian modes like walking or cycling) does not have a certification process underpinned by agreed European or worldwide standards so far. This lack of certification labels has the negative impact of holding back the deployment of GNSS-based services and thereby impeding the attainment of the expected benefits.

The COST Action SaPPART is a direct response to these issues and will:

  • establish a bridge between GNSS and ITS communities, gathering the high-level or even best European experts in the two fields, from both academic and professional origins, fostering the common comprehension of the problems and the solutions to solve them.
  • act as a scientific reference centre and will have the capability to link any specific problem with the best European research team possessing the necessary expertise to solve it.
  • support all initiatives aiming at making use of GNSS systems for road transport and personal mobility services in difficult conditions, providing them with reference documents and guidelines for implementing their specific GNSS application.
  • propose a comprehensive framework for the definition of the performances of the GNSS-based positioning terminals used in ITS and personalmobility, and the necessary test procedures to assess these performances.
  • Through its dissemination programme, SaPPART will contribute to a better understanding of the potential and limitations of GNSS in the road transport and personal mobility sectors.
