Abstract
A multi-scale decomposition and reconstruction architecture is defined on the basis of the empirical mode decomposition(EMD) theory,and the systematic errors mitigation model is demonstrated.A standard of the scale selection for the systematic errors elimination is given in terms of the means of the accumulated standardized modes.Then,the scheme of the GPS/PLs baseline solution based on the EMD is suggested.The experimental results show that the proposed scheme dramatically improves the reliability of ambiguity resolution and the precision of baseline vector after systematic error eliminated.
