| 摘 要： | 讨论了测量融合组合导航的两种方法，提出并研究了应用极大似然的估计的测量融合方法，并将该方法与基于线性一均方估计的测量融合方法作了比较。仿真研究表明测量融合方法在组合导航系统中具有良好的应用价值，特别是基于极大似然估计的测量融合方法，充分利用了测量值的冗余信息，其融合效果更好，组合系统的精度也有较大幅度的提高。

| Abstract: | Two measurement fusion methods for integrated navigation system are discussed.A measurement fusion technology using maximun likelihood estimator is proposed and compared with the technology based on linear mean square estimator.The simulation shows that the measurement fusion technology is of practicable value to integrated navigation system,especially the technology based on maximum likelihood estimator,which makes full use of the measurement redundancy information,and can increase the accuracy of integrated navigation system. |
