Electronic device for calibrating geomagnetic sensor, and method of operating electronic device

An electronic device comprising:

• a geomagnetic sensor;
• memory configured to store a plurality of instructions;
• a motion sensor;
• and
• at least one processor operatively connected to the geomagnetic sensor and the motion sensor,
• wherein the plurality of instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
• obtain a plurality of geomagnetic signals from the geomagnetic sensor;
• determine to perform calibration of the geomagnetic sensor when a magnitude of a geomagnetic signal among the plurality of geomagnetic signals exceeds a preset value;
• based on determining to perform the calibration, identify a motion of a user based on motion data obtained using the motion sensor;
• based on the identified motion of the user, determine a range of magnitude to be used for calibrating the geomagnetic sensor;
• extract geomagnetic data corresponding to geomagnetic signal having a magnitude within the determined range of magnitude among the geomagnetic signals;
• and
• calibrate the geomagnetic sensor based on the extracted geomagnetic data.
