摘要
介绍了一种惯导系统真航向角精度的试飞评估方法。用GPS信息计算出飞行航迹作为参考基准,准确测出惯导系统输出的航迹角误差,以此间接评估惯导系统的真航向角精度。试飞结果表明,该方法科学可行。
This paper presents a method of flight test evaluation for true heading accuracy of inertial navigation system. The accuracy of the true heading angle of the inertial navigation system is evaluated indirectly by the flight track value which is calculated by the information of GPS. The flight test results show that the method is feasible.
