Coningerror and quantizing error are two kinds of primary errors in the attitude algorithm of laser strap-down inertial system.
圆锥误差和量化误差是激光捷联惯性导航系统姿态解算误差的两个最主要的误差源。

It was shown that the conic error can be compensated by two-sample iteration algorithm with high-frequency vibration. The precision of SINS can be improved by coning compensation.
