| Abstract: | In view of the model error in the fitting,the BP neural network is adopted to process the data including the element of certainty question,which can enhance the purification precision of the quasi geoid purification.A case is given in the local geoid purification in Jiaozuo,in which the fitting precision of BP neural network achieves the ideal results. |
