摘　　要：载波相位测量是全球导航卫星系统(GNSS)实现高精度定位的一个重要观测量。在现阶段,自动驾驶、智慧城市等领域的技术越来越成熟,高精度定位能在这些领域得到广泛的应用,甚至促进这些领域的快速发展,是当前卫星导航领域的热点。快速可靠地确定整周模糊度是载波相位测量中的关键,也是提高GNSS定位精度的关键。本文整理了各种整周模糊度的解算方法,其中重点论述了三频载波模糊度解算(TCAR)方法、递进模糊度整数解算(CIR)方法、最小二乘模糊度去相关平差(LAMBDA)算法等整周模糊度的解算方法及其研究进展,并探讨后续研究的方向。Carrier phase measurement is an important observation for the global navigation satellite system(GNSS)to achieve high-precision positioning.At present,technologies in fields such as autonomous driving and smart cities are becoming increasingly mature,and high-precision positioning can be widely applied in these fields,even promoting their rapid development,which has currently become a hot topic in the field of satellite navigation.Quickly and reliably determining the ambiguity of whole cycles is a key factor in carrier phase measurement and can improve GNSS positioning accuracy.This article summarized various methods for solving the ambiguity of whole cycles,with a focus on the calculation methods and research progress of the ambiguity of whole cycles such as three-carrier ambiguity resolution(TCAR),cascade integer resolution(CIR),and least-squares ambiguity decorrelation adjustment(LAMBDA),and the article explored the direction of subsequent research.
