摘要
提出了一种基于多天线GPS 载波相位测量的捷联惯导系统静基座初始对准方法。给出了观测方程的详细推导过程,该观测方程中三个失准角均直接可观。最后给出了卡尔曼滤波仿真结果。结果表明,该方法极大地改善了捷联惯导系统静基座初始对准中方位失准角的估计收敛速度和精度。
A new initial alignment method for SINS stationary base is proposed which is aided by multi-antennas GPS carrier phase measurement. The deducing of observation model is presented. In the new observation model, the angular misalignments are directly observable. This method is evaluated by Kalman filter simulation. The simulation results indicate that the new method greatly improves the convergence speed and the precision of the azimuth misalignment estimation for SINS initial alignment on stationary base.
