GPS全球定位系统在试飞试验中的应用

The Application of GPS Global Positioning System in Flight Test

笔者主要介绍了使用GPS(Global Positioning System)数据对试飞试验中的载机目标指示误差进行评估的方法,并可进行GPS轨迹作图辅助分析试飞效果。选取典型事例介绍了该方法的详细分析流程及数据分析具体步骤。该方法可操作性强、分析结果可靠,已被广泛应用于各试飞试验中,具有较大的工程实际应用价值。

The method of error analysis on target indication in flight test is introduced,and the flight effect is analyzed with flight track,by using GPS data.The flow and steps of this method are introduced by a typical case.This method is operational and reliable,and used in flight test widely with a higher engineering application value.
