摘　　要：提出了一种利用Google Earth二次开发能力实现飞机三维航迹监视和六自由度飞行仿真的新方法。使用KML语言描述飞机三维航迹和飞行姿态,通过Google Earth提供的可扩展接口引入飞机监视数据得到Google Earth上的飞机实时三维航迹及六自由度飞行仿真。系统采用B/S架构,客户端采用Google Earth浏览器,全部开发都在服务器端。提出了一种用飞机前后两个位置点空间连线矢量提取飞行姿态算法。用这种方式得到三维航迹简单直观,既可以用于三维航迹研究分析、实时航迹监视、六自由度飞行仿真,还可以作为一种新的航班动态查询工具。This paper introduced a novel method of 3D flight track and 6-DOF flight simulation based on secondary development of Google Earth. 3D flight track and 6-DOF flight simulation, described by KML markup language, were presented by introducing real-time surveillance data of flight into Google Earth via its extendable interface. The system was built on B/S architecture, and the entire development was put on the server while the clients used Google Earth browser directly. An algorithm to extraet flight attitude from a space vector, which was eonneeted by two track points, was proposed. The results indicate that 3D flight track derived by this way is simple and intuitionistic, which could not only be applied to the research and analysis of 3D flight track, real-time flight track, 6-DOF flight simulation, but also be used as a new query tool of flight information.
