针对航天测量船外弹道测控系统中影响测控精度的误差源众多、作用机理复杂、测量船现有方法难以从数据残差中自动辨识误差的难题,在给出外测数据轴系参数误差传递模型的基础上,提出了基于误差传递基函数开展匹配追踪的测量船误差溯源方法,通过误差的迭代辨识,匹配误差,定位误差,并准确估计误差值,实现测量船误差的自动识别,提高船载设备误差辨识的效率和精度。仿真分析结果证实了该方法的正确性和有效性。
Aiming at the problem of many error sources, complex mechanism of action and difficulty of automatic measurement of error in data residual by the existing methods of shipboard ballistic measurement and control system in aerospace measurement and control system, Based on this, a tracking error tracking method based on error transfer basis function is put forward. Through iterative identification of error, matching error and positioning error, the error value is accurately estimated to realize the automatic identification of measuring ship error, Error identification efficiency and accuracy. The simulation results confirm the correctness and validity of the method.
