The article studies relevant problem of real time monitoring - the availability of the required GNSS navigation characteristics, which is required for railway rolling stock traffic automation. As prototypes, the main approaches to monitoring the availability of the required navigation characteristics of WAAS EGNOS wide area differential systems users were analyzed. It was shown that the use of the total probability of violation of the required navigation characteristics without decomposition of an equivalent range error is an appropriate approach for building the algorithm for monitoring the availability of navigation support for transport applications. The method of monitoring the availability of required navigation characteristics was proposed for automated railway traffic control tasks.
