基于航线数据库的自适应导航系统

The Adaptive Navigation System Based on Flight Courses Database

飞行的导航与制导是保障飞行任务的重要条件。文章分析了基于航线数据库的导航制导系统,介绍了指令式的制导方式,即自适应的制导系统,它是首先测量飞机的运行状态,并将数据传给存有航路数据的计算机,经比较后,得出飞机飞行与预定航线的偏差,从而得出控制舵面运动的指令,将指令传到飞机舵面,飞机自动控制调整航向及姿态。

The navigation and guidance is an important safeguard to the flight. The paper analyses the navigation system based on the computer which contains the flight courses datum. It introduces the navigation system base on the struction,that is,the adaptive navigition system.The sensor detects the position and the velocity of the plane and transmits the information to computer ,the computer disposes the information and compare it with the flight courses database and the differences between the position of the plane and its schedule flight courses will be made.Then the struction will be produced to controll the rudders of the plane.So the plane will automatically adjust its courses and position to fly along the schedule courses.The paper introduces the principle and its hardware form of the adapitive controller.
