Abstract

Absolute positions of global position system (~GPS~) enabled mobile communications devices, which form a wirelessly networked group of GPS
mobiles, can be determined at each of the mobiles based on use of wireless communications capabilities of the mobiles for obtaining relative positioning information or range measurements for the mobiles of the group. Although the mobiles of a group cannot establish line of sight (~LOS~) communications signal reception paths with a sufficient number of GPS satellites to permit each mobile to determine its absolute position solely based on GPS signal transmissions, the mobiles can compute their respective absolute positions and the absolute positions of other mobiles if a predetermined number of LOS paths can be established and based on the obtained range or relative positioning information.
