摘　　要：为解决电离层活跃期的周跳探测问题,根据无几何无电离层组合特性,构造3个线性无关的三频伪距载波相位组合作为周跳检验量,并以相位电离层残差二阶差分值作为周跳修复验证量。通过对电离层活跃期内全球导航卫星系统(global navigation satellite system,GNSS)三频观测数据进行处理,验证算法的可靠性和有效性。结果表明:算法可以有效地探测与修复在电离层活跃期内的三频周跳,并适用于三频实时动态的周跳处理。In order to solve the problem of cycle-slip detection in the active period of the ionosphere,three linearly independent triple-frequency pseudo-range carrier phase combination have been constructed as cycle-slip inspection quantity according to the characteristics of geometry-free and ionosphere-free combination and the repair value is validated by second-order time-difference phase ionospheric residual combination.The reliability and effectiveness of this algorithm have been verified by processing triple-frequency GNSS(global navigation satellite system)observation data during the active period of the ionosphere.The results show that this algorithm can effectively detect and repair triple-frequency cycle-slip during the active period of the ionosphere,and it’s suitable for triple-frequency real-time dynamic cycle-slip processing.
