Abstract

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.
