| Abstract: | Aiming at the situation that there is single gross error in the observation vector of the Errors in variables(EIV) model, we propose the robust total least squares method. On the basis of the generalized maximum likelihood estimation, we use the observation vector residual function which grows more slowly instead of observation vector squared residuals items, and have deduced robust total least squares estimation calculation formula with the iteration method with variable weights. Finally, we apply the new method to the coordinate transformation parameters determination, and verify the feasibilities of the new method. |
