Abstract：Based on the algorithm of vector sum and maximum polyhedron volume satellite selection algorithm,a satellite selection method based on partition vector sum is proposed.The method is as follows:(1) according to the elevation angle and azimuth angle in earth-fixed coordinate system,the visible satellite area is divided into the top area and some base areas;(2) the base satellites are selected in base area,and the selected satellites'vector sums are computed,then the three sets of base satellites responding to the minimum sums are selected;(3) combining the base satellites with the top satellite from the top area,the satellite set,which has the minimum GDOP,is chosen.And the satellites of the set are taken as the positioning calculation satellites.The simulation results show that the proposed method can achieve fast satellite selection in the navigation and positioning with high accuracy.
