The geomagnetic matching methods depend on particular distribution of geomagnetic field.Navigation may be failure in the region lacking geomagnetic fluctuation.To satisfy the demand of globe geomagnetic navigation,an improved algorithm for matching of multiple characteristic parameters is presented.Multiple elements of geomagnetic field along the track are measured synchronously.A multi-objective MAD(Mean Absolute Difference) function is applied to measure the similarity,and the function is… Expand
Matching Suitability of Geomagnetic Aided Navigation Based on Spectral Moment Characteristics
A novel matching-area suitability assessment method for geomagnetic matching aided navigation is proposed, which is based on spectral moment characteristics. With the analysis of profile spectralExpand
