Rapid Re-Convergence Methods of Real-Time PPP When Satellite Cycle-Slips Occur Frequently under Seismic Monitoring Environment
Abstract In this paper, we use re-initialization of all satellites, additional ionospheric constraints and additional coordinate constraints to solve the above re-convergence problem. Based on real-time observations of NOTA station network, we test the three methods. The results show that they effectively improve positioning accuracy. In seismic monitoring, appropriate methods can be selected according to the actual situation to obtain high-precision real-time dynamic PPP processing results, thus better capturing seismic signals and improving the capability of seismic monitoring.
