For the INS/GPS error model, if the velocity errors can be measured by the information of the GPS, the observable degree of the vertical platform angle error become great enough to estimate the misalignments, when the aircraft have horizontal acceleration.
对于惯导系统的误差模型,如果有速度误差观测,只有在有水平过载的情况下,方位角误差的可观测度才比较大。
