摘要
粗差探测是北斗导航定位研究的热点内容之一,正确探测并处理粗差对提高定位精度具有重要意义。本文通过分析比较现有粗差探测方法的特点,提出利用电离层残差法进行粗差探测,并通过实验数据进行分析,结果表明该方法能够快速探测北斗卫星观测值中的粗差,为定位解算提供干净的观测值。
Outlier detection is one of the hot topics in Beidou navigation and positioning research. It is of great signifi cance to correctly detect and process outlier to improve positioning accuracy. By analyzing and comparing the characteristics of the existing methods,this paper puts forward the use of the ionospheric residual method for the detection of outlier,and through the analysis of experimental data,the results show that this method can quickly detect the rough difference in the BDS observation value and provide clean observation value for positioning calculation.
