基于RTKLIB的精密单点定位精度分析

Precision Single Point Positioning in RTKLIB Precision Analysis

针对PPP中误差改正项较多且难以具体编程实现的问题,为了验证RTKLIB数据处理软件相关模块改正效果,本文利用RTKLIB进行PPP解算,叙述了在PPP处理过程中对电离层、对流层、频间偏差等误差项采用的改正方法,并使用辽宁省阜新市某测站的实测数据进行了PPP实验。结果表明,利用RTKLIB解算静态PPP,可使定位精度达到厘米级,满足预期的解算精度。

In order to verify the effect of RTKLIB data processing software related modules,it is difficult to implement the error correction in PPP.Using RTKLIB data processing software for the PPP,elaborated in the process of the ionosphere,troposphere,frequency deviation between error correction methods,and utilize the measured data of Liaoning Fuxin one station carry on PPP experiments,the results show that using RTKLIB calculating static PPP,the positioning accuracy can reach cm level,satisfies the expected solution accuracy.
