组合导航系统中实时多任务的软件设计

本文分析了基于实时多任务体系的组合导航系统的软件结构，并根据组合导航系统的工作原理和需求分析，将组合导航系统软件划分为多个具有不同优先级的任务，并在嵌入式操作系统VxWorks上实现了组合导航系统的软件设计。目前项目组已应用这种实时多任务软件结构，显著提高了导航系统软件的可靠性、实时性和运行效率，较好地实现了组合导航系统的导航定位功能。

Real-time Multitask Software Design of Integrated Navigation System

A software framework of integrated navigation system based on real-time multitask is analyzed in the paper. According to its operating principle and demand analysis, the software of integrated navigation system is divided into several tasks with different priorities, and has been developed based on VxWorks, which is an embedded real-time multitask operation system. Our project team has applied this software framework and significantly improved the reliability, real-time and operation efficiency of navigation system software, hence accomplishes the navigation and positioning of this system.
