Coning error and quantizingerror 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。

Frequency measurement is usually implement by accounting the measured signals and standard signals, thus quantizingerror becomes the main source of measuring error.
