Abstract:
Many positioning methods (Relative Kinematic, Real Time Kinematic (RTK), Pricese Point Positioning (PPP) and Real Time (RT)-PPP etc.) based on GNSS sensor have been used to detect dynamic motions occurring on the earth. These methods used require external parameters such as a second GNSS receiver, internet connection, satellite orbit and clock correction information. In this study, the VADASE (Variometric Approach for Displacement Analysis Stand-Alone Engine) approach, which can directly capture dynamic motions in real-time without the need for any additional parameters, are examined. This method, based on multi-GNSS observations, was compared with the PPP method, with reference to the Relative Positioning(RP) method in the time and frequency domain. According to the results, it was seen that the dominant frequency values of vertical dynamic motions were the same for all three methods. While the amplitude values corresponding to the dominant frequency vary between 1.6 mm and 3.2 mm in the RT-VADASE method according to the RP method referenced in the experiments, this difference varies between 1.1 mm and 1.6 mm in the PPP method. In addition, when all experimental cases are examined in the time domain, there is a small (1-2mm) difference between the KOH values of the RT-VADASE method compared to the PP-PPP method. The results show that the RT-VADASE approach can accurately and reliably detect instantaneous vertical dynamic motions. However, it has been shown that the RT-VADASE method can be used as an integrated sensor in the early warning system in situations that will endanger human life by making a rapid hazard assessment of the structure in cases that may threaten the health of the structure, instantly detecting the effect of dynamic loads such as earthquake, wind, traffic load.
