Trends in the development of modern transport systems are oriented to the maximum speed increase and throughput of transport highways while maintaining maximum traffic safety. It is clear that this national economic problem is solved only due to automation of the train sheet control in transport highways. In its turn, automation of management processes transport operation can be implemented only on the basis of appropriate high-precision and reliable navigational and temporal support of transport objects and transport infrastructure. Currently there is an integration process of the means and sensors of navigation information into a single global navigation system, the main element of which is national satellite radio navigation systems. Development of national satellite radio navigation systems and their differential augmentations resulted in the construction of the world integrated global navigation system GNSS. In this connection, there are unprecedented opportunities to ensure high-precision navigation, synchronizing time scales and implementation of engineering and construction surveys. However, there are also serious problems in the integration of national GNSS components, such as GPS, GLONASS, BeiDou, Galileo and other navigation systems.
This article focuses on a brief overview of a set of problems that must be solved al the level of the national satellite radio navigation systems for their successful entry into GNSS and the implementation of highly efficient navigation and temporal support for automated intelligent transport systems on this basis.
The prospects and problems of the development of Russian radio navigation system GLONASS are assessed separately. They are required to be solved for effective use of the GLONASS means when solving problems of constructing automated transport systems.
