摘要

在GPS基线解算中

LambdaZ变换以其快速高效性成为模糊度搜索算法中提高算法性能的有效算法.但在观测方程协方差阵严重病态的情况下

LambdaZ变换可能有变换失败的情况

提出测试补偿Z变换算法

用于规避LambdaZ变换失败的风险.通过分析其在短基线解算中的执行表现

给出测试补偿Z变换的适用范围和性能评估.执行结果表明

算法在协方差阵病态情况下能提高变换成功率.

Abstract

The lambda method with Z transformation is valid and fast.It has been widely used to enhance the performance of the search arithmetic in GPS data processing problem.However

the lambda Z transformation is face to the probably of invalidation when the condition number is large.Propose a new arithmetic called test and compensated Z transformation to avoid the risk of invalidation.Though the performance of test and compensate Z transformation in processing measured data

it is clear that this new arithmetic perform well and success rate of Z transformation can be enhanced.
