Today localization stock is performed with track circuits, axle counters, which are characterized by low reliability and high cost. The development of global satellite navigation systems offers new opportunities for solving the positioning task. To get to this application must be answered a lot of questions, the main of which are related to the provision of necessary safety.

Existing global positioning systems (US GPS and Russian GLONASS) does not satisfy the stringent ments of the insurance of railway equipment. Accuracy in many cases is not reached d safety levels. Users haven’t information about good working order of the system and how much they can trust a particular position. The latter is already beginning to be overcome with the construction of the European Geostationary Navigation Overlay Service EGNOS and in particular introduced in 2011 a service SoL (Safety of Life), which monitors the integrity of the system. Such service will offer currently developing a European navigation system GALILEO.

This paper evaluates the capability of meeting the ments of rail reliability and safety through sharing of EGNOS and GALILEO. Analyzes and calculations show that the possibility is real.
