舰船用多惯导配置导航系统数据处理研究

Research on data dispose of multiple INS configuration navigation system on ships

针对舰船上配置的2套或多套惯导系统,本文设计的阻尼方式能够起到提升精度指标要求,更好地调整阻尼处理所用时限、宽容外来速度偏差的目的。这是根据惯导特性,分析原有的阻尼方式的基础上,全新设计的一套方法。对各类误差和阻尼的关系进行了比较分析,利用仿真模拟,较好地对2套或多套阻尼进行误差结果比较,从而对新设计的阻尼方案有了进一步的验证。

For the two or more inertial navigation systems on the ship,the damping mode designed in this paper can raise the longitude index,adjust the time limit of damping treatment and tolerate the external velocity deviation.This is a new design method based on the analysis of the original damping mode according to the characteristics of inertial navigation system.By simulation,two or more sets of damping are compared with each other,and the new damping scheme is further verified.
