APPLICATION OF WEIGHTED TOTAL LEAST SQUARES IN ITRF TRANSFORMATION
加权总体最小二乘方法在ITRF转换中的应用

According to the fact that the points in two transformational coordinate systems are all affected by random errors,which make the observation vector and coefficient matrix in error equations both include errors,and even,these observations and elements in coefficient matrix may be heteroscedastic and correlated.We employ the weighted total least squares solution to calculate the parameters of ITRF transformation.To demonstrate the performance and efficiency of the application of WTLS solution in coordinate t...
