EXTENDED KALMAN FILTER BASED AUTONOMOUS MAGNETOMETER CALIBRATION

Title:

EXTENDED KALMAN FILTER BASED AUTONOMOUS MAGNETOMETER CALIBRATION

Document Type and Number:

WIPO Patent Application WO/2016/074153

Kind Code:

A1

Abstract:

Systems and methods may provide for obtaining first sensor data associated with a gyroscope (22) and obtaining second sensor data associated with a magnetometer (10). Additionally, the first sensor data, the second sensor data and an extended Kalman filter may be used to calibrate the magnetometer (10). In one example, a sampling rate of the magnetometer (10) is increased before obtaining the second sensor data and the sampling rate of the magnetometer (10) is decreased after calibration of the magnetometer(10).
