摘要 在LAMBDA方法搜索GNSS双差模糊度的基础上,根据单历元模糊度搜索的特点,提出了一种多历元动态快速确定模糊度的方法——Ratio值累积法。介绍了利用Ratio值累积法逐步确定宽巷模糊度、L1和L2载波相位模糊度的技术,用实例证明该方法集成了单历元整周模糊度搜索速度快、简单,多历元模糊度确定可靠性高的优点。 On the basis of LAMBDA method and the characteristics of single epoch ambiguity resolution, this paper proposes a method of multiple epoch ambiguity resolution Ratio Accumulation Method and then introduced the wide-lane ambiguity resolution and L1 and L2 ambiguity resolution using Ratio Accumulation Method. At last, the results of examples indicate that Ratio Accumulation Method has advantages integraling single epoch ambiguity resolution＇ s simplicity and high reliability of multiple epoch ambiguity resolution.
