摘　　要：为了提高三轴地磁传感器测姿系统的精度,采用了温度补偿的方式对传感器输出进行误差补偿。分析了地磁传感器温度误差产生的机理,依此建立了三轴地磁传感器温度误差补偿模型,并根据此模型进行了相关的误差补偿实验。通过对比补偿前后的实验数据,可以得出结论:该温度误差补偿方法能有效减少由于温度因素对传感器输出造成的影响,提高三轴地磁传感器测姿系统的精度。In order to improve the precision of attitude measurement system of three-axis geomagnetic sensor,temperature compensation is used to compensate the error of sensor output,the mechanism of temperature error of geomagnetic sensor is analyzed,and a compensation model of temperature error for three-axis geomagnetic sensor is established based on this model,and relevant error compensation experiments are carried out according to this model.The experimental data before and after compensation are compared.It can be concluded that the temperature error compensation method can effectively reduce the influence of temperature factor on the output of the sensor and improve the precision of the attitude measurement system of the three-axis geomagnetic sensor.
