摘要
周跳检验量的构建是实现周跳探测与修复的根本。本文在详细阐述伪距相位组合基本原理的基础上,研究了该组合周跳检验量的选取标准。根据选取标准优化组合系数,然后联合STPIR组合得到最优周跳检验量。最后,利用北斗三频实测数据设计相关实验对该周跳检验量进行验证。验算结果表明:根据本文方法所构建的周跳检验量在探测与修复周跳上具有良好的效果,可以探测出原始观测值中的任意周跳。
The construction of cycle-slip test is improtant for cycle-slip detection and repair.On the basis of the principle of pseudo-phase combination,the selection criteria of cycle-slip combination test are studied in this paper.According to the selection of the standard,the combination coefficients are optimized and combined with STPIR combination,then the optimal cycle-slip test is obtained.Finally,this cycle-slip test is verfied by some experimenst using BeiDou triple-frequency measurement data.The results shows the cycle-slip test constructed by this method in this paper has a good effect on detecting and repairing cycle-slip,and could detect any cycle-slip in the original observation data.
