GNSS整周模糊度研究现状与展望
Research status and prospect of GNSS ambiguity of whole cycles
摘要
Abstract
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.关键词
