GPS Networks for Structural Monitoring: From Highway Bridges to Mach 10 Rails

Michael Hyzak, Camille Tucker, Keith Duff

Abstract:	GPS technology has advanced to the stage where it is now a cost effective tool for structural deformation monitoring. Applied Research Laboratories, The University of Texas (ARL:UT) has been developing GPS-based deformation monitoring systems over the past five years. These have been applied primarily to large highway bridges and to the Holloman AFB High Speed Sled Test Track (HHSSTT). In previous papers [Duff and Hyzak, 1997; Hyzak, Leach, and Duff, 19971, the authors have described the system architecture and results from testing on bridges. This paper focuses on system configuration for the HHSSTT and analysis results from several months of continuous data collection. Results indicate that, while position accuracies at the few millimeter level are being achieved, some system configuration changes are needed to reach the goal of 1 millimeter or better.
