Magnetic navigation using the Earth's magnetic anomaly field has proven to be a promising alternative that can provide coverage for a navigation system. This research demonstrates a magnetic navigation system using an extended Kalman filter (EKF) to aid an aircrafts inertial navigation system (INS). Traditional magnetic anomaly navigation uses a static calibration method, which takes post-processed data to calibrate, obtaining the Tolles-Lawson coefficients needed for magnetic anomaly navigation filter compensation. These coefficients are constant and may cause drifts in the navigation filter if not re-calibrated. The online calibration method continuously updates the Tolles-Lawson coefficients as a filter state, reducing the need for calibration flights. This research uses F-16 data to demonstrate the effectiveness of this method.
