SYSTEM FOR TRACKING AND LOCATING AN OBJECT USING A CELLULAR NETWORK
First Claim
1. A position isolation system comprising:
- at least one portable cellular transmitter adapted for wireless data communication via an associated cellular communication system;
activation means for selectively initiating data exchange between the at least one cellular transmitter and an associated tracking station via the associated cellular communication system, wherein data of the data exchange obtains additional position data representative of an associated, cellular relay system through which the cellular data exchange is made so as to allow for isolation of a location of the at least one portable cellular transmitter in a limited geographic region; and
a secondary transmission system associated with the at least one portable cellular transmitter, wherein the secondary transmission system is adapted for outputting information representative of secondary location data having a positioning resolution within that of the limited geographic region.

Abstract
The present invention is directed to a position isolation system comprising at least one portable cellular transmitter adapted for wireless data communication via an associated cellular communication system. Data exchange between the at least one cellular transmitter and an associated tracking station is initiated via the associated cellular communication system. The data exchange obtains additional position data representing an associated, cellular relay system through which the cellular data exchange is made, enabling isolation of the location of the portable cellular transmitter in a limited geographic region. The position isolation system also includes a secondary transmission system, associated with the portable transmitter, that is adapted for outputting information representing secondary location data. The secondary location data has a positioning resolution within that of the limited geographic region.
