Adequately using the results of CQG2000,integrating GPS level data,and introducing the remove-compute-restore(RCR) method to calculate the elevation abnormality of unknown points is superior to only adopting GPS leveling.In this paper,the detailed calculation process is given,and the fitting model is separated into function model and statistical model to explain.Finally,with examples,the feasibility of the method is illuminated.
