| Abstract: | The algorithm of the outliers eliminating and gravity matching selection is presented based on maximum correlation. The new algorithm can eliminate large numbers of interferential data through the constraint condition and it 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 simulation proved the algorithm is effective. |
| Keywords: | gravity matching theory of maximum correlation outliers matching selection |
