Application of Modern Geodetic Technologies and Satellite Positioning Systems in the Survey of Railway Stations

Abstract

The article presents methods of shooting train stations when performing a tool check of plan and profile station tracks in accordance with existing regulations. The normative requirements, measuring means, shortcomings of existing technologies of instrumental check of the plan and a profile of station ways and possibilities of the modern technologies based on 3D models and pos-sibilities of their application for the Railways are considered. The necessity of the presentation of railway tracks and infrastructure in digital form (3D) is substantiated. The concept of digital data on railway track and elements of infrastructure should be invested not by picket, but by three-dimensional geodetic coordinates, which will allow the railway track and its elements to be dis-played in digital space. Fragments of reporting documentation are shown. The perspective developments for full-scale survey of station ways made on the basis of UAV and complex "Profile" are considered, the results of experimental and methodical works received in 2018g on railroad ZS are given, positive conclusions are drawn.
