| 摘 要： | 在对飞参记录系统的方向舵偏角通道进行标校的过程中,俯仰角变化和其它非线性误差都会影响电子罗盘的测量精度。本文研究了基于曲线拟合原理建立误差补偿公式的方法,以减小方向舵偏角通道的测量误差。实验证明,这种方法可以有效地提高电子罗盘的方向舵偏角测量精度。

| Abstract: | In the calibration of angle of rudder channels,both the change of pitch angle and other nonlinear errors affect the measurement precision of electron compass.An error compensation formula is proposed based on the principle of curve fitting,which can reduce the measurement errors of the angle of rudder channels.The experiments verify that this method can improve the precision of electron compass in measuring the angle of rudder. |

| Keywords: | angle of rudder nonlinear error curve fitting error compensation |
