GPS速度法确定飞机空速系统位置误差

飞机空速系统位置误差的测定，飞行试验中有多种常规方法，但期精度只能满足常规型号空速系统的验证要求。针对这一问题提出了ＧＰＳ速度法，叙述了该方法的原理、实施过程和数据处理方法，讨论了方法的系统精度并给出了误差估算结果。通过对某型飞机的验证试飞，表明该方法简便易行，可满足气动补偿型空速系统的试飞验证要求。

Using GPS system to determine the position error of pitot static system

Usually, there are many methods which may be used to determine the position of the pitot static system. But most of them have not enough accuracy to test the new type of the pitot static system. In order to solve this problem, this paper put forward a new method: the speed method using GPS system. The principle of using GPS system to determine the position error is described. After discussing the accuracy of method, the course of test and the data process with some results from flight test is also provided. Because of the high accuracy, this method can be used to test new type of the pitot static system.
