Abstract
This paper is focused on the performance of Global Navigation Satellite System (GNSS) Kinematic Precise Point Positioning (PPP) methods for monitoring the engineering structures based on harmonic oscillation tests using a single-axis shake table. To examine the performance of kinematic PPP methods, shake table oscillated harmonically for different amplitudes and frequencies. Data were processed using the online Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP) service. Results were analyzed by time series analysis and Fast Fourier transform techniques. The kinematic PPP method's accuracy under different satellite configurations was determined by comparing the frequency and amplitude values obtained by PPP processing with the linear variable differential transformer (LVDT) results. As a result of experiments, the effectiveness of the multi-GNSS high-rate kinematic PPP methods in determining the structural movements were demonstrated and the frequencies of the structural movements could be determined exactly and their amplitudes with a maximum difference of 3.9 mm.
