摘要
Abstract
Geomagnetic navigation precisely obtains positions from geomagnetic field information. In order to obtain precise positions and filter stability, the poor observability of measured geomagnetic data was analyzed, the singularity exponent was used to measure the amount of geomagnetic information, the performance index was built using gross information and increasing factors, and flight route planning for geomagnetic aided navigation was researched using a singularity exponent. Finally, performance was compared using the flight simulation along different routes with a particle filter as the geomagnetic filter algorithm. The simulation results show that aided navigation routing planned using this algorithm has better positioning accuracy, filtering stability, and convergence.关键词
