Study of Ways to Improve the Accuracy of Determining the Coordinates of Rolling Stock Based on the Methods of Passive Location and Direct Determination of Coordinates

This paper is devoted to the study of ways to improve the accuracy of determining the parameters of the movement of rolling stock. Research of this kind is aimed at the possibility of owning accurate information about the location, characteristics of the train and adjusting its movement in real time to increase the capacity of railway sections. Increasing the capacity of the railways is dictated by one of the trends in the development of the economy of the Russian Federation. The paper analyzes the possible ways of determining the parameters of rolling stock movement, the result of which is the expediency of using satellite navigation systems for specified purposes. After identifying the main problems of using satellite systems, an alternative approach has been proposed, which consists in integrating navigation methods through self-determination and passive location based on difference-distance and radial-difference-difference methods for simultaneous measurements of a marker signal. The result of the work is an example of the application and calculation of the accuracy characteristics of an optimal algorithm for estimating motion parameters based on simultaneous acquisition of information which tells about the effectiveness of its application to the tasks of determining the motion parameters of rolling stock used in the systems for controlling the interval position of rolling stock. The volume of work - 55 pages, the number of tables - 2, the number of images - 10.
