直接利用两水平失准角快速收敛的估计结果对传统多位里对准中方位失准角的估计，提高了捷联惯导系统静基座对准的精度和速度。-Two level losing accuracy angle rapid convergence directly the estimate result to traditional many to the position losing accuracy angle estimate, thus increased the precision which and the speed greatly the strapdown inertial navigation system static base aims .
