Navigation Using Vector and Tensor Measurements of the Earth's Magnetic Anomaly Field
Abstract
As a means to navigate in a GPS-denied environment, a navigation filter is presented that uses measurements of Earth's magnetic anomaly field to aid an inertial navigation system (INS). An Extended Kalman Filter (EKF) is used to match magnetometer measurements to a specific location on magnetic field maps. A simulation trade-study is presented to highlight the advantages of using vector or tensor measurements of the anomaly field to aid the filter as opposed to other signals, such as scalar measurements of the anomaly field.
