Abstract:Since the quality of the solution of the Tikhonov regularization(TR) method is too dependent on the determination of the regularization parameters and less stable when solving ill-conditioned problems in the field of geodesy by TR method, an improved iterated Tikhonov regularization (ITR), combined with generalized cross-validation(GCV), can effectively overcome the above shortcomings.The calculation example results show that the ITR-GCV method is better in terms of solution accuracy, stability, and anti-interference.
