Research on the Methods of CMONOC CORS Station Time Series Analysis
Tian Lian · Geospatial Information · 2014
Taking the Wuhan CORS station for object, we used the ARIMA model and FFT model to fit the Wuhan station's about ten years' time series. According to the results, we can see that both ARIMA model and FFT model are good at fitting the Wuhan station time series. However, ARIMA model is very strict in theory and fits stably. FFT model is better in studying on the spectrum periods of the time series.
