双频方法在北斗三频周跳探测中的应用

Dual-frequency Method in the Application of BEIDOU Triple-frequency Cycle-slip Detection

为了能够更加准确、有效地检测北斗三频数据中的周跳,根据多频组合理论,采用消电离层三频无几何组合,并结合使用两个双频方法:MW组合法、电离层残差法,从而构成三个组合系数线性无关的组合观测量,对北斗三频载波观测数据进行周跳的探测。并通过实验仿真验证,论文的方法能够探测出北斗三频数据中包括不敏感周跳在内的所有周跳组合。

In order to detect the cycleslip of BEIDOU triple-frequency accurately and effectively,according to the theory of multiple frequency combination,eliminate the ionosphere triple-frequency geometric-free combination is chosen,in combination with dual-frequency MW combination and the ionosphere residual combination,the three combination coefficients are linearly independent combination,On BEIDOU triple-frequency data of cycle-slip detection.And through the experimental simulation,this method can detect all the cycle-slip of BEIDOU triple-frequency,including not sensitive cycle-slip combination.
