Abstract

The invention provides a system and method for tracking one or more objects (11). The system of the invention includes tags (2) that are attached to the objects to be tracked that transmit a signal. Antenna modules (10) receive the signals transmitted by the tags and inputs the signals into a processor (8). The processor calculates from the signals a current location of each tag and then compares the current location of the tag with one or more previously calculated locations of the tag to determine whether the tag is undergoing any movement.
