simulink中分析频谱的有效工具，可以分析连续，离散信号的频谱(simulink an effective tool in the analysis of the spectrum, can analyze the continuous, discrete signal spectrum)

This work outlines the application of ground-based GPS to climate research and meteorology without omitting the fact that precise GPS positioning can also highly benefit using numerical weather models for tropospheric delay determination for applications where GPS troposphere estimation is not possible, for example kinematic and rapid static surveys. In this sense, the technique of GPS-derived tropospheric delays is seen as mutually improving both disciplines, precise positioning as well as meteorology and climatology
