1. An entity tracking system comprising:
- a wireless identification component configured to receive a plurality of messages conveying an identification of an entity;
a position determining component configured to determine a plurality of corresponding geographic locations of the wireless identification component, wherein each of the plurality of corresponding geographic locations being a respective geographic location of the wireless identification component when each of the plurality of messages is received; and
a processor configured to;
determine a plurality of corresponding geographic positions of the entity based on the plurality of corresponding geographic locations of the wireless identification component and a known spatial relationship defining a distance and orientation between the position determining component and the wireless identification component, wherein each of the plurality of corresponding geographic positions of the entity being a respective geographic position of the entity when each of the plurality of messages is received; and
detect a change in geographic position of the entity based on the plurality of corresponding geographic positions of the entity.

Abstract
A method for tracking an entity is disclosed. In one embodiment, a plurality of messages conveying an identification of an entity are received using a wireless identification component. A geographic location of the wireless identification component is determined by a position determining component wherein the geographic location describes a respective geographic location of the wireless identification component when each of the plurality of messages is received. A geographic position of the entity is determined based upon a known spatial relationship between the position determining component and the wireless identification component.
