ABSTRACT:
Relative positions of a plurality of mobiles communication devices, which form a wirelessly networked group of mobiles, are determined at each of the mobiles of the group without the need for external positioning information obtained from a location remote from the actual locations of the mobiles of the group. The relative positions are determined at the mobiles of the group based on mobile-to-mobile range measurements, distance and direction of movement measurements and altitude measurements made at the respective mobiles.
