评价GPS相位模糊度整数解正确性的严密方法

Rigor Method on Evaluating the Rightness for the Integer Solution of GPS Carried-phase Ambiguity

针对如何评价模糊度整数解的正确性 ,指出了基于传统的假设检验理论的三步法存在的理论缺陷 ,介绍了模糊度归整域的概念和可容许整数估计的定义 ,并在Teunissen关于可容许整数估计原定义的基础上给出了更为严密的新定义。基于这个新定义 。

This paper points out the theoretic pitfall caused by evaluating the rightness of integer ambiguity solution based on the three-step approach of the traditional hypothesis test theory, and introduces the concept of the pull-in region for ambiguity and the definition of the admissible integer estimation. On the basis of the original definition for the admissible integer estimation, a new severer definition is given. On the basis of this new definition of the admissible integer estimation, the concept of ambiguity success rate is discussed and the corresponding formulas are deduced.
