| Abstract: | Geomagnetic matching algorithm is the core of geomagnetic navigation.The geomagnetic matching results can be used as observed input of combined filter,also directly as the output of system location results.The geomagnetic field characters and basic principle of geomagnetic matching are introduced briefly.With Hausdorff distance as similarity measure criterion and measured data as geomagnetic reference map,a geomagnetic matching algorithm is introduced,and detailed flow chart is presented.Simulation results ... |
