Abstract:	The aim of this study is an analysis of the availability of the EGNOS service for a land mobile user, which is limited by the shadowing of the EGNOS satellites by the various obstacles. The shadowing process is modeled by the Markov process with model parameters determined for various environments by the mobile experimental measurements. The relevance of the model was also tested experimentally and the adequate conformity was observed. The availability of the EGNOS message reception in various environments was experimentally investigated and the statistics were calculated. The realized experiments have shown that the EGNOS service strongly depends on the environment and the full coverage cannot be guaranteed for the land mobile user. Safety-of-Life service in problematic areas should be ensured by the additional system e.g. augmentation by the inertial navigation system. In the frame of this project the special experimental equipment based on the Experimental GNSS Receiver with Software Radio architecture was developed. The use of parallel signal processing enabled to reach the 8 ms response of the receiver on the EGNOS signal.
