| Abstract: | Geomagnetic Matching Navigation Algorithm(GMNA) is an important factor to influence the navigation precision,to some extent GMNA determines the navigation precision.An excellent GMNA should not only fulfill the precision demand but also the time.First,in this paper GMNA based on point was studied,which is unsatisfied with the real-time due to the long time of position.Aimed to the problem which exists in GMNA based on point,GMNA based on the vector was proposed,which is satisfied with the real-time needed to the navigation system.The former two navigation algorithms are both based on the single point,which makes them have the same defect:the matching is not unique.Taking into account of this,the GMNA based on the Monte Carlo was brought out,which is on the basis of the line,and could overcome the defect by means of the restriction among the points.The simulation results were showed and attained some benefit conclusion. |
