Abstract
With the development of Precise Point Positioning (PPP),PPP has been grad-ually developed by the float resolution stage to ambiguity resolution stage.PPP Ambiguity Resolution (PPP-AR)has become the research focus.Moreover,FCBs product is the pre-condition of the PPP-AR.However,research on station selection strategy of FCBs products is not sufficient,based on the data quality assessment parameter of data integrity rate,wide-lane ambiguity residuals and integrated data quality of single satellite,this paper put forward a method,which used global grid method to select the tracking station.The results show that the accuracy of FCB product which used 40 station is equal to the accuracy of FCBs product which used 230 station and greatly reduce the time which are used in calculating the FCBs products.关键词
