一个新的GNSS模糊度估计类

A New Class of GNSS Ambiguity Estimators

  • 摘要: 介绍了一类新的GNSS模糊度估计。因为该类遵循移去恢复原理,称之为整数等变估计类。本文将说明整数等变估计类较整数估计类和线性无偏估计类的范围要大,同时给出一个相当有用的整数等变估计类的表达式。这个表达式揭示了整数等变估计类的结构,并显示该表达式如何在浮点解的基础上实现整数等变估计。最后还提出最优整数估计。

     

    Abstract: A new class of GNSS ambiguity estimator is introduced in this paper.This class is referred to as the class of integer equivariant(IE)estimators since it still obeys the important integer remove-restore principle of integer estimation.It is shown that the IE-class is larger than the class of integer estimators as well as larger than the class of linear unbiased estimators.We will also give a useful representation of IEestimators.This representation reveals the structure of IE-estimators and shows how they operate on the ambiguity float solution.Finally, the best integer equivariant estimation is proposed.
