分析了平台伺服电路零位和框架轴上干扰力矩引起其水平两轴航向效应漂移的机理，以及利用正交弹性漂移补偿电路减小此项航向效应漂移的机理，并通过试验测试表明：此项航向效应漂移可达0.20(°)/h，采用正交弹性漂移补偿电路后可减小到原来的十分之一以内。

In this paper,the principles that how the null positi on of servoloop and the disturbing torque of gimbal axes cause the heading sens itive drift of two horizontal axes,and why the quadrature spring rate amplifier can compensate it are analyzed.From the testing results,it is found that this heading sensitive drift can reach 0.20 (°)/h,and can be red uced to 10% or less by using the quadrature spring rate amplifier.
