Objective Considering the accuracy of gravity matching is influenced by heading and gravity field,thestatistical characteristics of the gravity field are calculated by a moving window to select a gravitymatching area,and the correlation between the accuracy of gravity matching and carrier heading isconfirmed.Then,the skeleton points of matching areas are extracted by a fast Euclidean distance fieldalgorithm and a simplification algorithm to form local areas with their distance values,so by calculat-ing the gravity statistical characteristics of these local areas,the carrier can select headings with highgravity matching accuracy.Finally the validity of this analysis method is verified with simulation re-sults.
