Construction of GPS Station Noise Heteroskedastic Model Based on Load Effect
Abstract To quantitatively evaluate the time series noise of GPS station coordinates that may be caused by load effects, we propose a temporal noise modeling method to describe the temporal correlation and heteroscedastic properties of noise. The results show that the proposed noise model is superior to FN+WN and AR noise models and can effectively quantify the heteroscedastic characteristics of white noise and quantitatively describe the variation trend of noise content before and after load correction.
Key words :
loading effects
coordinate time series analysis
AR model
heteroscedasticity
