摘要:

导航数据库可用于导航计算、导航台自动调谐管理和辅助完成飞机实时定位等,是飞行管理计算机所必需的数据源。为了开发高逼真度的飞行模拟视景系统,设计了一种基于World Wind 的导航数据库并进行实现。数据库包括机场、跑道、仪表着陆系统、测距仪系统等信息,可实现全球导航数据的查询、修改与显示以及飞行计划的控制与显示,并最终在World Wind 中实现所有信息的三维显示。以数字高程数据及高清遥感影像为视景模型,结合飞行模拟插件,并借助于World Wind 平台,完成了一套以该数据库为基础的飞行模拟视景系统。

关键词: 导航数据库, 飞行管理计算机, World Wind, 飞行模拟视景系统

Abstract:

Navigation database is necessary data sources for flight management computer which can be used for navigation calculation,auto-tuning management of the navigation station,and the real-time location of aircraft,etc.To develop high-fidelity flight simulation visual system,a navigation database based on World Wind is designed and implemented. This database includes the information about airports,runways,instrument landing system,and distance measuring system,etc. So the global navigation data can be queried,modified and displayed,also the flight plan can be controlled and displayed. Finally all information will be displayed in World Wind by three-dimension. Digital elevation data and high-definition remote sensing images acting as visual model,a flight simulation visual system based on the database is completed by the WW platform combined with a flight simulation plug-in.

Key words: navigation database, FMC, World Wind, flight simulation visual system
