Abstract：This paper mainly uses the interval quartering algorithm of singular spectrum analysis iterative to do interpolation about GPS coordinate time series. This method extracts main characteristic components from an incomplete time series of coordinates by an adaptive filter. Based on the improved singular spectrum analysis iterative interpolation, it is then compared with the Lagrange interpolation method. Our research shows that the interval quartering algorithm of singular spectrum analysis iterative not only has higher interpolation precision, but also solves the interpolation efficiency problem. The computational efficiency is greatly improved.
