SYSTEM FOR BUILDING DATA BASE OF RAILWAY OBJECTS Russian patent published in 2002 - IPC

FIELD: railway transport. SUBSTANCE: invention relates to measuring systems and it can be used to build electronic data base of railway objects and to check position of rolling stock. Said system consists of "n" navigational satellites, control-and-guide station and rolling stock in which radio navigational parameters are recorded and image of railway objects and current time are recorded on video tape. Radio navigational parameters are simultaneously recorded at control-and-guide station. When processing the data, radio navigational parameters measured at movable object are corrected, and code railway objects is introduced when viewing video tape. Code of railway objects and their geographical coordinates are saved in memory. EFFECT: possibility of locating objects in track coordinates. 3 dwg
