One advantage of the future European satellite system Galileo compared to existing GNSS will be guaranteed performances up to a very high level. By providing such a guarantee Galileo sets a more reliable base which is often necessary to certify and use safety-critical applications which depend on this system. Besides Galileo other techniques including augmentation systems like SBAS and GBAS provide promising results to improve stand-alone GNSS making them potentially applicable in safety-critical domains.
The GNSS Center for safety-critical applications, certification and services GAUSS at the research airport in Braunschweig was founded in 2006 in the frame of the initiative „Satellite Navigation“ of the state of Lower Saxony, Germany. It bundles the competences of its member companies in the area of safety-critical GNSS applications.
The first major cooperated project of GAUSS was the European GALCERT project. Funded by the Galileo Supervisor Agency (GSA) it aimed at developing a Green Paper for the certification of the Galileo Signal in Space (SIS). In 2007 GAUSS started the „GAUSS Basisprojekt“ (GAUSS-BP). It is funded partially by the Ministry of Economics and the Ministry of Science of Lower Saxony, Germany, and brings together research and industry partners in the field of certification for safety-critical GNSS applications. From the industry side these are Aerodata, etamax Space, ITS Niedersachsen, NavCert, Oecon and TÜV Nord Cert. The academic partners are the Institute of Transportation Systems of the DLR and the Institute of Flight Guidance as well as the Institute for Traffic Safety and Automation Engineering of the Technische Universität Braunschweig.
While GALCERT focused on the satellite system Galileo and its Signal in Space, the base of any applications to come, GAUSS-BP as a follow-up project explicitly focuses on the application itself. One of it aims was to analyse the fundamentals of the certification processes in different transportation domains, as avionics, rail, road and partially maritime and the differences and similarities between them.
This paper presents the results and the ongoing work of the GAUSS-BP project towards a unified certification process for safety-critical GNSS applications for multiple transportation domains.
