| 摘 要： | 分析了PANDA软件精密单点定位的数据处理策略,并采用SDCORS网 81个测站2012年第一周的GPS观测数据进行静态精密单点定位处理,通过得到的各测站年积日001～007的单天解进行统计分析,验证了该软件在山东区域进行精密单点定位的精度及可靠性。通过对比分析,研究了不同卫星截止高度角、不同对流层映射函数、不同星历钟差产品以及不同观测数据时长对其精密单点定位精度的影响。结果显示，当卫星截止高度角设置为10°、采用GMF对流层映射函数、利用精密星历和钟差、观测数据时长超过18 h时,PANDA软件静态精密单点定位的精度能够达到2 cm.

| 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. |
