However, care was taken to adjust the coordinate system for variation in the length of both a degree of latitude and a degree of longitude over the limited distance to the target. The technique used has an estimated error of about 10m in absolute target positioning (over about a 50km range). 2) WGS-84 datum were used for all position determinations.
