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。
During calibration of the rudder deflection channel of the flying record system, the change of pitch angle and other non-linear errors will affect the measurement accuracy of the electronic compass. This paper studies the method of establishing the error compensation formula based on the curve fitting principle to reduce the measurement error of the rudder declination channel. Experiments show that this method can effectively improve the electronic compass rudder deflection measurement accuracy.
