Abstract

GPS-RTK offers direct three-dimensional coordinates measurements for structural health monitoring, but the measurements accuracy and reliability can not meet high building vibration monitoring requirements for multipath influence, cycle slip, low sampling rate and other factors. On the other hand, accelerometer offers precise, high sampling rate acceleration observations in structural vibration monitoring. Aiming at making full use of the two kinds of sensors, a Kalman filtering method with the integration of GPS and accelerometer is researched, which is of multi-rate filtering and robust features. The experimental results show that: this method can effectively improve the accuracy, reliability and sampling rate of high building vibration monitoring.
