重力匹配导航系统可靠性研究

Research on the Reliability of Gravity Matching Navigation System

  • 摘要: 介绍重力匹配导航系统的组成和导航的实施步骤,从影响匹配结果的几个因素出发,利用信噪比、地形熵、相似度三个特征组成的特征向量来判定匹配结果的可信度。仿真结果表明,该导航系统能够有效地解决惯性导航系统误差随时间积累的问题。

     

    Abstract: The composition of gravity matching navigation system and implementation procedure of navigation is introduced. Based on the factors that influenced on the result of matching, and signal-to-noise, terrain entropy and likeness degree are used to determine the reliability of matching result. The simulation result shows that this navigation system can solve the problem that inertial navigation system error is accumulative.
