根据多频组合理论,构造基于北斗三频数据的无几何、消电离层组合,结合双频MW组合法和电离层残差法,对北斗实测三频数据进行周跳探测。实验表明,上述3种组合的结合使用能探测出所有大小的周跳,并具有较好的修复效果。
Based on multi-frequency combination theory, and using dual-frequency MW and ionospher- ic residual methods a triple-frequency geometry-free and ionosphere-free combination is built to detect cycle slips. With real data of BDS triple frequency, it is shown that all cycle-slips can be successfully detected and repaired with these three combination observations.
