摘要
A method of determining a direction of a triaxial electronic compass oriented in a specific direction by using the triaxial electronic compass and an inclination sensor, the method includes obtaining an elevation angle of the specific direction from the inclination sensor to switch a selection of two output values from the three output values to another selection of two output values therefrom; determining a geomagnetic aspect from the two output values; obtaining a rotational angle about an axis extending in the specific direction from the inclination sensor; calculating a deviation angle of the direction of the triaxial electronic compass which is caused by the selection switching, in accordance with the elevation angle, the geomagnetic aspect and the rotational angle; and correcting the direction of the triaxial electronic compass in accordance with the deviation angle.
