Abstract
A method comprises providing a vehicle landing pad with a reference frame origin at a center thereof, and X and Y axes through the reference frame origin; arranging a first group of markers, each having a first size, on the pad such that the first group of markers form a first convex hull about the center of the pad; and arranging a second group of markers, each having a second size less than the first size, on the pad such that the second group of markers form a second convex hull within the first convex hull. The first and second groups of markers are located symmetrically with respect to the center of the pad along the X and Y axes so as to yield a position estimation solution for landing a vehicle having a highest accuracy when compared with placing markers at other locations along the X and Y axes.
