Abstract
(EN) An electronic device, according to one embodiment disclosed in the present document, comprises: a communication circuit that performs communication with an external device; a magnetic sensor that measures geomagnetism; a memory; and a processor, wherein the processor may: acquire magnetic measurement values by using the magnetic sensor; when the magnetic measurement values are stored in the memory more than a specified number of times, calculate a score of the magnetic measurement values; when the calculated score is equal to or greater than a first reference value, determine a first parameter and a second parameter related to the magnetic measurement values; determine an error between the magnetic measurement values and the second parameter by using the first parameter and the second parameter; when the error is equal to or less than a second reference value, determine the intensity of a reference magnetic field on the basis of at least one of the first parameter and the second parameter; and store the reference magnetic field in the memory according to a specified condition. Various other embodiments inferred from the specification are also possible.
