摘　　要：为了更好地探测载波相位观测值中的周跳,求解整周模糊度,本文针对文献[1]中提出的利用双频载波相位观测值求差进行周跳探测与修复的方法,进一步分析了周跳与载波相位观测值及伪距观测值的关系,增加了三个约束条件,进一步完善了该方法对周跳的探测和修复能力,并通过实例验证了其实用性。In order to better detect cycle slip of carrier phase and resolve integer ambiguity, and in view of the method of cycle-slip detection and reparation by dual frequency different carrier-phase proposed in the reference paper , this paper analyzes the relationship between carrier-phase and pseudo-range. Meanwhile, three constraints are added. And thus, the capacity of this method to detect and repair cycle-slip is thereby improved. Finally, some examples are given to prove that.
