The magnetometer includes three sensors, including a Hall Effect sensor associated with a first sensing axis and a sensor of another type associated with a second sensing axis. The method includes: maintaining a cache of gyroscope data and magnetometer data representing magnetometer readings obtained from the magnetometer; detecting a temperature event; determining an expected magnetometer reading following the temperature event; comparing the expected magnetometer reading to a magnetometer reading obtained from the magnetometer after the temperature event to determine a calibration correction amount; compare a difference between the magnetometer reading obtained after the temperature event and the expected magnetometer reading for the second sensing axis to a threshold and, based on the comparison to the threshold, generating new calibration data for the magnetometer based on the calibration correction amount."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration of temperature effect on magnetometer","description":"A method for calibrating a magnetometer following a temperature event is described.
