Abstract
A method involves determining estimated positions for multiple cells within a region using cellular signals received by a receiver at multiple known receiver positions. Multiple first cell groups are determined using the multiple cells. Respective estimated positions are determined for each cell group of the first cell groups. Each cell group of the first cell groups is validated using the respective estimated position of each cell group and the known receiver positions. Multiple second cell groups are generated based on the cell group validation. An estimated position of each cell group of the second cell groups is used as an estimated position of a respective base station within the region, and a base station almanac is updated using a respective estimated position for each of the base stations.
