摘要
提出北斗测向系统的测量数据改正到导航系统中心的计算方法,解决北斗测向系统在动平台导航系统航向检测中存在的误差问题,建立北斗测向系统数据改正模型,通过实测比对证明改正后检测结果精度明显提高。文中方法对北斗航向测量系统使用具有一定的指导意义,便于动平台导航系统航向指标检测,能够扩展北斗测向系统在动平台刚体情况下的应用范围。
The calculating method is put forward that the data of BD direction determination system is corrected into the center of the navigation system. The error problem is solved when BD direction determination system is used to test the navigation system of the moving platform. The model is built, which can be used to correct data from BD direction determination system. The precision of the result is obviously improved through the real test. This method will be very meaningfully used for BD direction determination system, which is more conveniently used to test navigation system of the moving platform. At the same time the method can be used to expand the range of BD direction determination system through the firm moving platform.
