摘要
Abstract
The errors such as clock error,ionospheric delay and tropospheric delay in precise point positioning(PPP)can be accurately corrected,but multipath is difficult to correct effectively.The experimental results of strong multipath environment and weak multipath environment of different materials show that multipath has little effect on the positioning accuracy of long-time observation,but has a great influence on the convergence time in a short time.Then,the Sunday repetition characteristic of multi-path is analyzed,and the influence of multi-path is weakened by setting a certain cutover height angle,filtering and so on.关键词
