摘要(Abstract)：
针对BDS/GPS双差组合数据解算需要考虑观测数据周跳探测与修复能力的问题,该文研究了BDS/GPS双差组合观测数据周跳探测与修复方法。该方法根据基线长短采用不同周跳探测与修复手段,对于20 km以上的长基线采用三差后的双频观测值进行无电离层线性组合和宽相线性组合的双频周跳探测方法,然后分别以三差后的无电离层线性组合残差值和载波双频残差平均值作为周跳探测检验量;对于20 km以下的短基线采用单频周跳探测方法,利用三差后的载波L_1或L_2的残差值作为周跳检验量,利用该方法进行周跳探测与修复实验。结果表明,BDS/GPS双差组合观测数据周跳探测与修复方法可以有效探测并修复GPS卫星和北斗的GEO、MEO、IGSO卫星观测值中存在的周跳。
