RTKLIB 软件静态精密单点定位精度测试与分析
Static Precise Point Positioning Accuracy Test and Analysis of RTKLIB Sof tware
摘要
Abstract
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 .关键词
