摘要
针对Doppler/SINs组合导航系统在飞行状态下的导航精度较差的问题,提出了利用载体作匀速圆周运动的初始对准方法.该方法可以快速估计出sINs的平台失准角并能提高对平台失准角的估计精度,可以较大幅度地缩小对平台失准角估计的稳态极限值。模拟试验验证了该方法的可行性和有效性,具有较好的工程应用前景。
An in-flight alignment algorithm was proposed by utilizing a uniform circular motion of the aircraft to improve the accuracy of Doppler/SINS integrated navigation system in flight condition.With the proposed theory,the platform error-angles of the SINS can be estimated quickly,the estimation accuracy can be improved and the steady-state limit of platform error-angles can be greatly narrowed down.Simulation experiment verifies the feasibility and effectiveness of this theory which has a prospect engineering application value.
