摘　　要：在飞行器航迹模拟中,距离70 km以上的航迹就必须考虑地球曲率的影响,采用地球椭球假设的航迹模拟是合理的解决办法。讨论球面上两点最短路径航迹模型和水平航向机动模型不仅具有实用意义,也是地理坐标系下产生复杂航迹的基础。In the aircraft track simulation,the influence of earth curvature should be considered when the track range exceeds 70 km.The track simulation based on the ellipsoid hypothesis of earth is a reasonable resolution method.The discussion of the track model of the shortest path between two points on the sphere and the horizontal course mobile model is not only of applied meaning,but also is the base to generate the complex tracks under the geographic coordinate system.
