The kinematical equation of the probe and the equation of measuring error caused by the swaying of the measuring arm are established. 建立了測頭的測量運動方程和關節晃動引起的測量誤差的方程。
Because of the high spinning rate, a small fluctuation in the scale factor of the gyros will cause marked errors in the spinning angle, which invalids the measurement. 因為火箭彈的自旋角速度較高，所以陀螺標度因子的微小變化將引起自旋角度很大的測量誤差，使測量結果失去意義。
