Safety Related Usage of Satellite Based Positioning Systems in Transportation - Concepts for Certification

摘要

For localisation purposes within safety related transportation applications, the upcoming European Navigation System GALILEO will provide a wide range of opportunities and challenges. It will be the first global satellite based positioning system that can meet the advanced requirements of all different modes of transportation. For this new area of usage, new questions arise in the field of fulfillment of the specific safety requirements of each transportation mode. These can be answered either separately for each mode by setting up requirements in respect with the existing regulations and taking into account the new specific parameters and characteristics of the new system. This leads to four (mainly) independent sets of regulations, requirements and, in consequence, to four different sorts of components to be used, i.e. one in each domain resulting into a high amount of costs and effort. A more sophisticated approach (partly) integrates the four domain specific sets of requirements and regulations by means of identifying a generic kernel. After that, for each mode, the individual specific characteristics of the modes can be incorporated in domain specific instantiations or extensions. This procedure requires only a single (joined) initiative to work on but offers also (on the side of the suppliers) the chance to broaden the market for safety related positioning devices or components in transportation. Suppliers would be able to take the advantage of using their products for multiple transportation modes by re-using the "generic core certification" independently. For the practical evaluations, a generic reference receiver can be implemented, to fit these requirements.
