摘要
为了评估整周模糊度求解精度,首先介绍了整周模糊度概率特性的基本理论和z变换的基本思想。对直接归整法和序贯归整法整周模糊度概率特性进行了分析,探讨z变换对序贯归整法整周模糊度概率特性的影响。给出了一个基线解算实例。得出了z变换优化整周模糊度概率特性的结论。
To evaluate ambiguity probabilistic we introduce the theory of GPS ambiguity probabilistic evaluation and z transform first. Then we discuss the probability of Integer Rounding and Integer Bootstrapping. Base on that,we make research on the z transform influence in GPS ambiguity probabilistic evaluation and take out an example of a baseline for analysis. Finally, we draw the conclusion that z transform will improve GPS ambiguity reliability by meliorating ambiguity's probabilistic evaluation.
