Kurzfassung:

This paper presents a new approach for specification modeling of GNSS-Positioning Systems by means of ontology-based-System Engineering. The objective is to afford safety-critical railway applications based on GNSS-positioning. The latter shall be realized by giving requirements-engineering of railway transportation domain the possibility to formulate their needs in their own terminology but to translate them to a common physically-based terminology afterwards. This physically-based terminology shall be used by developers of GNSS-positioning systems (e.g. receivers) to meet the appliers’ demands from the railways. The main problems may be stated as follows: 1. A common syntax and semantic for description of terminologies 2. Method to define and formulate interfaces between domain-specific and GNSS terminology 3. Definition of common physically-based terminology, compatible to GNSS specifications. Each traffic mode, as railway, automotive and aviation, holds its specific terminology to specify requirements concerning e.g. accuracy and availability of positioning. At railway transportation there exist different standards exactly specifying the needs and requirements to positioning for their safety-related applications. Furthermore the upcoming Galileo-System is presently specified using terminology from aviation-technology. Considering these transportation domains there is a lack of interfaces between the respective terminologies to enable the developers of GNSS positioning systems to fulfill the appliers’ specifications. To overcome these problems due to different terminologies, here an approach is presented which is based on UML as a method for describing terminologies, ontological formalisms and the relations between different terms. As result this paper demonstrates accordingly modeled terminologies of rail and aviation domains and their linguistic interfaces which shall be the basis for further development of a physically-based common terminology.
