为满足通用航空器对结构简单、价格低廉的导航系统的需求，提出一种机载便携式导航系统方案。系统以航路图作为背景，通过标定技术实现航图像素坐标与经纬度坐标的配准，并通过对航图的分割与四叉树管理，降低了对设备内存的需求，随着航空器位置更新，系统通过平移、旋转航图实现对航空器的导航。仿真实验结果表明，航空器在航图上定位精确，系统对于航图的平移、旋转响应准确，便携式导航系统可以满足通用航空器导航的需求，对通航飞行安全提供了一定的技术支持。

To meet the requirements of general aircraft for a navigation system with simple structure and low cost, a solution of portable navigation system was proposed as avionics. In this system, the air route map was selected as the background; the map calibration technology was used for registration between the pixel coordinates and latitude and longitude coordinates; with the map division and the quadtree management, the demand of equipment memory was reduced; with aircraft”s position updating, the translation, rotation of map could realize the navigation function for aircraft. The simulation results show that aircraft locates on the air route map exactly; the response of system for the translation and rotation of air route map is accurate; the portable navigation system can satisfy the requirements of general aircraft navigation, and provide some technical support for general aviation flight safety.
