北斗定位系统在飞行试验中的应用研究

Beidou Position System Application for Flight Test

摘要:

为了解决使用美国商用GPS对我国飞行试验中定位精度和速度的种种限制以及对我国国防安全的潜在危险,文章基于我国日趋成熟自主研发的北斗定位系统技术,开展其在飞行试验中的研究；文中分别对北斗的短报文通信技术、单点及事后差分技术、实时差分技术在飞行试验中的应用方法进行研究,并介绍了飞行试验中北斗定位数据的处理方法；通过试验数据与美国商用GPS数据进行对比,结果显示北斗定位系统精度与美国商用GPS精度接近；最后展望了北斗定位系统未来在我国飞行试验以及国防、科研以及交通运输等民用领域的广阔应用前景。

Abstract:

To solve the problem of the GPS technique limitation of USA such as positioning accuracy and quick positioning, and potential danger in national defense, Beidou system in flight test was studied based on the developing capacity of Beidou system in national defense. The application of the message communication technology、point positioning、post difference and real time difference of Beidou system in flight test were introduced, and method of process Beidou Position data was discussed. The article compared the data of Beidou with GPS data in flight test, the result showed that the accuracy of Beidou data could be comparable with that of GPS; finally the application prospect of Beidou in military and commercial field were discussed.
