摘　　要：由于很难获得全面真实的导航飞行轨迹数据,而各类导航系统性能测试又必须要有飞行轨迹数据和惯性器件的输出参数。针对捷联惯性导航系统进行测试的飞机仿真飞行轨迹的设计方法。方法将飞行轨迹分解成若干任务段,根据实际需要,通过自由组合这些任务段,得到一条完整的飞行轨迹。据此设计了一条仿真轨迹并对该轨迹进行了性能分析,结果表明设计方法不仅能够较好的模拟飞机的实际飞行状态,更能有效的检验捷联惯性导航算法的精确性和可靠性,应用效果令人满意。Because the comprehensive and actual flight track data and inertial component output parameters can＇t be obtained easily, but the capability test of the Strap - down inertial navigation systems needs these data, therefore, a design method for simulating flight track of aircraft is introduced to detect strap - down inertial navigation system. This method divides flight track into some task segments, according to the practical condition, the task segments can be combined randomly to form an integrated flight track. Based on the method, a simulation track is designed, and then the track performance is analyzed. The results show that the design method can not only simulate the actual flight state of aircraft better but also test the accuracy and the reliability of strap - down inertial navigation algorithm effectively. The application effect of the method is satisfactory.
