摘　　要：介绍了精密单点定位的基本原理及常用组合量,利用日本东京海洋大学研发的开源软件RTKLIB进行静态精密单点定位数据处理,采用事后、快速、超快速三种星历及钟差产品对某IGS站单天观测值进行解算,并将处理结果和准确值对比。结果表明事后和快速产品单天解收敛曲线基本一致,最终收敛值X、Y、Z三个方向偏差在4cm左右,完全满足一般精度要求的工程需要;采用超快速产品Y方向上偏差较大,表明超快速产品对该软件的定位精度有一定的影响。T he paper introduced the basic principle of Precise Point Positioning and com-monly used combination value .It used the open source software RTKLIB developed by To-kyo University of Marine Science and Technology to process static PPP data .Some IGS sta-tion single day observed value was calculated with the IGS ,IGR ,IGU three ephemeris and clock products ,and compared the results with the accurate value .The results show that IGS and IGR products single day solution convergence curves are basically no difference ,and the final convergence value deviation of X ,Y ,Z three directions are about 4cm .It fully meets the needs of the general project accuracy requirement .However ,the IGU product caused Y direction deviating seriously ,which shows that IGU product has certain impacts to the posi-tioning accuracy of this software .
