Virtual lab based on co-simulation to include impairments of wireless telecommunication such as GSM-R in the evaluation of ERTMS.

Summary The deployment of the European Rail Traffic Management System (ERTMS) is mandatory along European railway corridors, but it will follow a long and expensive process. Thus, there is a need for faster roll-out and reduction in cost for the certification and authorization necessary to put equipment into service. One of the solutions to accelerate the process relies on making intensive use of lab-testing before real deployment. The ANR VEGAS project, labeled by i-Trans will design, develop and evaluate a virtual laboratory based on co- simulation by connecting an ERTMS functional simulator with a simulator dedicated to telecommunication technologies evaluation. In this way, the co-simulation will allow evaluating the functional subsystem behavior while taking into account the impairments related to the telecommunication subsystem (radio propagation impairments such as bad radio links and cuts, electromagnetic interferences or attacks). This paper presents the ongoing work on this virtual laboratory, the preliminary results and interesting prospective work in this context.
