附有基线长度约束的单频数据单历元LAMBDA方法整周模糊度确定

Ambiguity Resolution of Single Epoch Single Frequency Data withBaseline Length Constraint Using LAMBDA Algorithm

摘要: 针对某些GPS动态定位中基线长度精确已知的特性,提出了附有基线长度约束的LAMBDA方法,同时在实践中使用两步搜索,对LAMBDA方法进行了优化。实测数据处理结果表明,该方法对LAMBDA方法的改进效果较为显著,能在基线长度已知条件下较高成功率地确定单频单历元数据的整周模糊度。

Abstract: This paper puts forward LAMBDA algorithm with baseline length constraint and a two steps search method. The results of six examples show that the baseline length constraint and a two steps search method evaluate LAMBDA algorithm.
