For localisation purposes within safety related transportation applications, Galileo will provide a wide range of opportunities and challenges. It will be the first global satellite based positioning system that can meet the requirements of all different modes of transportation. For this new area of usage, new questions arise in the field of fulfilment of the specific safety requirements of each transportation mode. These can be answered 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 (mainly) four independent sets of regulations, requirements and, in consequence, to four different sorts of components to be used i.e. one in each domain. 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. For dealing with standards, requirements and (e.g. regulative) specifications, a formal description will be helpful for gaining independence for natural (and mode specific) languages and for providing transparency and consistency. Additionally, it gives the possibility of formal checks of the described (modelled) objects. 21.12.2005, 08:56 2/2 iVA, TU-BS U:\Projekte\ZERTIFIKAT\Veröff\2006-0404-CERGAL\Pbn_2005-11-30_Abstract-CERGAL-2006_1-0_Hä.doc This paper shows a concept for this approach in the field of (joined) certification of positioning systems for transportation applications. To complete and technically outline the concept, two hardware platforms (one for road and one for rail transportation) are shortly presented, which can be applied for the processes for evaluation of the safety related positioning systems.
