ABSTRACT: The UAV navigation system's performance is improved through embedding the geography information model that can process the vector map data in the system by using MapX, In this paper, how to navigate and plan the UAV flight course in the vector map is investigated. The basic control and operation for vector map in the geography information system is introduced, and the flight course is designed and modified in the map. In addition, 2D vector map can't orient UAV in 3D space, so the altitude model is added in the UAV navigation system to realize 3D orientation by integrating 2D vector map with altitude plot. The simulation results in the UAV simulation system indicate that the navigation system can monitor and control UAV efficiently and intuitionally.

使用MapX在无人机导航系统中添加能够处理矢量地图数据的地理信息模块，可以显著地提升系统的性能；文章对如何在矢量地图下进行无人机导航与任务规划进行了研究，完成对地理信息系统中矢量地图的基本控制和操作，并在地理信息图上进行航线的设定与修改；另外，针对二维矢量地图无法对无人机进行三维空间定位的问题，文章通过在无人机导航系统中添加高度位置显示模块，用二维平面地图与高度图相结合的方式来实现对无人机位置的三维定位；通过在无人机仿真实验系统中的使用，证明了该系统能高效、直观地对无人机飞行进行监视与控制。

Just under this background, studying on the flight mechanism of flapping-wing MAV and sample fabrication from the bionics are conducted in this dissertation. The kinematics equations of insect wings can be acquired by the observation and measurement on the natural insect in researching paper. The geometry model of insect is established by UG technology. The three dimensional grid during the insect moving in the flow field is achieved which adopted grid generation method. The characteristic of lift and drag are attained by simulation the surround flow field during the locomotion of wings, and the flight mechanism of insect is discussed. Based on this study, the physical flapping-wing MAV is fabricated by the acquirable materials and parts of apparatus in existence.
