Research of GPS Height Time Series Improved by ARMA Model
Dang Ya · Beijing Surveying and Mapping · 2007
Autoregressive moving average (ARMA) method is applied to modeling GPS height time series of IGS fiducial stations. The paper calculated the linear velocities of before and after improved time series. And the velocities we get from improved time series is changed a litter but the precision is improved a lot. Through study, the noise of time series have decreased a lot compared to primary time series, and we can concluded that ARMA model is a good method for research GPS height time series.
