水面舰艇组合导航系统的工作模式与数据优化处理

Operation Mode and Optimized Data Processing of Integrated Navigation System for Surface Vessel

为了充分地利用各种信息源 ,并提高导航精度与可用度 ,水面舰艇综合导航系统一般设置了多种工作模式及相应的数据处理方法。本文以某工程型号任务为背景 ,提出了一种基于平台罗经、电磁计程仪及 L oran C定位系统等导航传感器的综合导航系统的工作模式及数据优化处理方法 ,经优化处理后的导航信息可有效地满足作战系统对导航信息 (尤其是对地速度信息 )的需求。仿真结果表明 。

In order to fully utilize all kinds of information resources and improve the accuracy and usability of navigation,several operating modes and corresponding data processing methods are set in integrated navigation system for the surface vessel.Based on a certain engineering development,this paper provides a kind of operation mode and corresponding data optimization method for the integrated navigation system composed of various navigation sensors (such as stabilizedgyrocompass,EN Log,LoranC,etc.).The optimized navigation in formation can effectivel satisfy the requirement of combat system on navigation information (especially on absolute velocity relative to the ground).The simulation results show that the data processing method can achieve the expected accuracy.
