This paper presents the first steps of developing the Galileo Satellite Communication Simulator (GSCS) based on the INET Framework [2] of OMNeT++ simulation engine [1]. We present our mobility model for the accurate prediction and modeling of satellite motion using NORAD's (North American Aerospace Defense Command) propagation algorithm SGP (Simplified General Perturbations) for real-time satellite position modelling. Galileo specific satellite orbit data is generated in order to establish the mobility of the prospective space segment. The validity of the simulation implementation is then proved by comparing the results of our simulation with two reputable satellite tracking applications and to a real GPS receiver, from which further extensions of the simulation system are derived. In further steps the integration in a Multiscale Network Simulation Environment is described. The dynamic interaction between Environment, Radio Channel and User Mobility can then be modelled in an adequate way.
