An Integrated Bridge Monitoring System Based on the GPS and Pseudolite Technologies

基于GPS和伪卫星技术的桥梁综合监测系统。全球定位系统(GPS)技术可用于精确测量建筑物、桥梁等人造结构的挠度。与传输类似全球定位系统信号的伪卫星(PL)的附加信号相结合，可以测量到监控点(S)的高度变化(S)，精度达到毫米级。与诺丁汉大学的研究人员合作，英国的一座桥梁结构将被用作试验床，这将是PLS首次用于此类应用。预期结果包括一套能够在线分析组合GPS-PL输出的变形监测算法。

An Integrated Bridge Monitoring System Based on the GPS and Pseudolite Technologies. Global Positioning System (GPS) technology can be used for precise deflection measurement of manmade structures such as buildings, bridges, etc. When integrated with additional signals from pseudolites (PL) that transmit GPS-like signals, changes in the height(s) of the monitored point(s) can be measured to millimetre accuracy. In collaboration with University of Nottingham researchers, a bridge structure in the U.K. will be used as a testbed, and will be the first time that PLs have been used for such an application. The expected outcomes include a suite of deformation monitoring algorithms capable of online analysis of the combined GPS-PL outputs.
