摘　　要：传统测试用飞行轨迹侧重于模拟飞机真实的飞行轨迹,其导航算法的局限性使得即使出现大的误差也可能无法察觉。改进了一种解析式测试用飞行轨迹的生成方法,设计了一条飞行仿真轨迹,并对轨迹进行了性能分析,指出了方法与传统的飞行轨迹设计方法的优劣。在指北式捷联惯导系统中,对惯性器件进行了建模并设计了惯导系统仿真软件。用所生成的飞行仿真轨迹对导航系统软件进行了测试。通过仿真比较,有效地验证了导航软件的正确性和可靠性。Traditional simulation flight track focuses on simulating an real aircraft flight paths, but it may cause big error because of the limitations of its algorithm. The paper improved a kind of method to create flight track and compared this method with the traditional trajectory design method to point out the advantages and disadvantages of these design methods. Based on the method, a simulation track is designed, and then the track performance is analyzed. Then a model for inertial component and an Inertial Navigation System Simulation Software were established and designed, and the software was tested with this flight simulation track. The result verified the accuracy and reliability of the software.
