| Abstract: | 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. |
