Real-time EGNOS monitoring

The paper deals with the real-time monitoring of the European Geostationary Navigation Overlay Service (EGNOS). Possible approaches to the monitoring are discussed at first. The rest of the paper presents the development of C++ software for real-time monitoring of EGNOS performance in the position domain. The software is intended to be used within the GNSS monitoring station run by the Department of Radio Engineering of the Czech Technical University in Prague. The base architecture and main blocks of the program will be described as well as possible outputs of the monitoring will be outlined.
