Abstract
High-rate GNSS plays an important role in monitoring the process of strong ground motion, such as seismic activity. To achieve real-time monitoring, a reasonable solution and filtering method are needed, especially for the 50 Hz data. Based on the analysis of differential and combination method, effects of ionosphere and troposphere have obvious trend within a short time, but cannot be treated as linear trend completely. To monitor real time surface deformation accurately, a newly developed strategy is proposed in this paper, it can effectively reduce atmospheric error of double-difference in real-time. 50 Hz data are obtained during Lushan earthquake (Ms7.0), Sichuan, China; the coseismic deformations are captured successfully on the sites of continuous operation reference station (CORS) stations. With 3D grid searching method, the obtained earthquake focus is basically consistent with USGS published results. It shows that the proposed method is effective and reasonable for strong ground motion monitoring by using high-rate GNSS observations, especially for seismic activity.
