摘要
实现周跳探测与修复的关键是构建最优的周跳检验量。在伪距相位组合法的基础上,根据北斗三频数据的特点,从理论上对最优组合系数的选取标准进行了详细地分析。通过对组合系数相关参数的对比,优选出两组最优系数,并联合相位电离层残差二阶差分(STPIR)组合构建得到最优周跳检验量。通过对北斗三频实测数据的处理验证算法的正确性和有效性。数值结果说明:算法能够正确有效地探测出不同频段上包括不敏感周跳在内的所有周跳并进行修复。
The construction of cycle-slip test is important for detection and repair of cycle-slip.On the basis of the principle of pseudo-phase combination,the selection criteria of cycle-slip combination test are analyzed in detail theoretically according the characteristics of Beidou triple frequency.By comparing the correlation parameters of combination coefficients,the two optimal combination coefficient were given,and the optimal cycle-slip test quantity was obtained by combined with second-order time-difference phase ionospheric residual(STPIR)combination.The correctness and validity of the algorithm is verified by processing the Beidou triple-frequency measurement data.The numerical results show this method can effectively detect and repair all cycle-slip in the different frequency bands,including insensitive ones.
