Algorithm realization and simulation of gravity matching aided navigation based on maximum correlation[J]. Optics and precision engineering, 2009, 17(4): 832-838.DOI:
The algorithm of INS/gravity matching integrated navigation is presented and analyzed
and an new gravity matching aided navigation algorithm based on maximum correlation theory is put forward. The new algorithm can subdivide the gravity map and eliminate large numbers of interferential data through the constraint condition in data gravity map searching process
and it can improve the algorithm of gravity matching based on maximum correlation effectively. The result of simulation proves that the new algorithm can be more effective and more adaptive to restrain the errors of the gravity data
to improve the orientation precision
to decrease the influence of Eotvos effect on gravity matching
and to speed up gravity matching for navigation in real-time. The algorithm of INS/gravity matching integrated navigation is more suitable for meeting the requirement of the actual underwater navigation.
