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 each of the mobiles of a group cannot establish
line of sight ("LOS") communications signal reception paths with more than three
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 range or relative positioning information can
be obtained.
