QualiSaR - Development of a Qualification Procedure for the Usage of Galileo Satellite Receivers for Safety Relevant Applications.
ENC 2012 - European Navigation Conference 2012, Gdańsk, Polen, April 2012.


This paper presents the concept of the just started European project QualiSaR. The project aims at the development of a qualification procedure that uses a reference system to determine the measurement quality of satellite-based localisation services. The qualification process is to be designed as a service for professional users developing sophisticated Galileo applications in order to certify receivers. The further development of satellite-based localisation systems leads to improved features and new functions, so that they can be used for more and more challenging tasks. Examples for safety relevant applications in road traffic are Advanced Driver Assistance Systems (ADAS) which shall finally be the base for automated driving manoeuvres. Their state-approved authorisation relies on the quantitative determination of the corresponding properties. Satellite-based localisation systems have been developed based on parameters from the aerospace domain. The created specifications are hardly compatible with the terminologies developed for ground transportation, metrology, and reliability. Currently, there are no approved methods to determine the corresponding parameters. Hence this project intends to establish a mobile and satellite-independent reference system. For the technical realisation of the reference system, on the one hand metrological qualification procedures in accordance with standardised metrological definitions and methods are necessary. On the other hand a terminological hierarchy covering localisation relevant terms is required. This will be developed in this project. Using the reference system, it will be possible to determine the identified metrological parameters in a typical application environment of ground transportation, independent from a certain environment. On this basis, the project will develop a standardisation document as a suggestion for technical committees and standardisation authorities like IEC and ISO
