基于World Wind的民航导航数据库设计及实现

Design and implementation of civil aviation navigation database based on World Wind

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须的数据源。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。

Navigation database is necessary data sources for flight management computer which can be used for naviga- tion 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 de- signed 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 dis- played, 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.
