| Abstract: | The algorithm of eliminating gross errors in robust estimation and gross error detection IQR criteria,and the orthogonal polynominal interpolation algorithm were studied.The experimental object is GPS single-day height time series of CORS fiducial stations in China from March 1,1999 to December 31,2009 lasting nearly 11 years.Through the gross error detection and interpolation tests of three selected base stations,the result shows that robust estimation is more effective than the IQR criterion to detect and... |
