Abstract
A location system for objects having location devices (16) as a means for repeatedly interrogating the location devices on each object to provide position signals. A means (18) to detect the position signals are provided. The position of each object and the area associated with each object are determined from the position signals and stored. The system is then able to determine the relative locations of the thus determined objects and associated areas.
