摘要
为了寻找合适的评估飞行试验中导航定位精度的方法,采用全球定位系统(GPS)作为基准,以两种不同的计算方法对长航时导航数据进行了统计计算,研究了两种方法的适用性。结果表明,在不同的导航时间范围内选取不同的计算方法,得到的结论才能够被用户和研制方接受。
In order to find an appropriate method of evaluating the position accuracy in flight test, by using the global positioning system (GPS) as a reference, long navigation time data has been calculated by two different methods, and the applicability of two methods has also been researched. Results show that by using different calculational methods in different extension of navigation time, conclusions could be accepted by users and developers.
