Abstract
A Railroad Surveying and Monitoring System configured on a mobile platform for surveying, monitoring, and analyzing rail position and superstructure and terrain substructure of railroad tracks (20a,b) or other structures. The system employs two or more High Accuracy Differential Global Positioning System devices (110,112), ground penetrating radar devices (116), terrain conductivity instruments (118), optical cameras (124), and data receivers and processors (126), which in turn process, display, and store the data in a usable database. Precise coordinate data generated from a High Accuracy Global Positioning System provides both location data for subsurface sensors and surface sensors and rail position coordinates to monitor track displacements during track inspection in real time.
