Abstract:     The data processing strategy of PANDA software precise point positioning are analyed,and using the GPS data of 81 stations in SDCORS network for the first week of 2012 to carry out the static precise point positioning. The single day solution of one week for each station are analysised,the accuracy and reliability of the software precise point positioning in Shandong area are verified.The effect of the precise point positioning accuracy on different satellite cut-off angle,different mapping function,different ephemeris products,different length of observation data are studied. The conclusion indicates that when the satellite cutoff angle is set to 10 degrees, using GMF mapping function, using the precise ephemeris and clock correction, observation data for more than 18 hours, PANDA software static precise point positioning accuracy can reach 2 cm.
