Telephone operable global tracking system for vehicles
First Claim
1. A global tracking system (GTS) for monitoring an alarm condition associated with and locating a movable object, the GTS comprising:
- a cellular telephone located with the movable object;
a GPS (global positioning system) receiver located with the movable object, the GPS receiver being effective for providing data reflecting a present spacial position of the movable object, in terms of spacial latitude/longitude coordinates;
an interface between the GPS receiver and the cellular telephone, the interface being connected between the GPS receiver and the cellular telephone and including circuitry for transmitting the spacial coordinates from the GPS receiver through the telephone, wirelessly to a remote location; and
an alarm for detecting that the object has been moved, by calculating a spatial movement of the object which exceeds a predetermined distance based on information supplied by the GPS receiver, and the alarm initiating the transmission to the remote location the spatial coordinates from the GPS receiver when said movement of predetermined distance has been detected.

Abstract
A tracking system for monitoring and locating vehicles includes a cellular telephone that is located in the vehicle, a global positioning system (GPS) receiver also located with the vehicle, and an interface unit between the global positioning receiver and the telephone. The global positioning receiver communicates with a system of satellites and provides continuous data, reflecting the present. spacial position of the vehicle in terms of its latitude/longitude coordinates. The interface between the GPS receiver and the wireless telephone includes a speech synthesizer circuit which converts the digitally encoded spacial coordinates into speech, which enunciates the position through the cellular telephone. By calling the vehicle cellular telephone from a remote location, the owner of the vehicle can hear the location of the vehicle, and then use that information to obtain its precise location.

16. A global tracking method for monitoring an alarm condition and locating a movable object, the method comprising:
-
outfitting the movable object with a cellular telephone; outfitting the object with a GPS (global positioning system) receiver for providing data reflecting a present spatial position of the movable object, in terms of spatial latitude/longitude coordinates thereof; interfacing the GPS receiver and the cellular telephone via an interface and using the interface to convert the spatial latitude/longitude coordinates to speech and transmitting the speech through the cellular telephone to a remote location; and detecting an alarm condition by calculating movements of the movable object which exceed a predetermined distance based on the data provided from the GPS receiver and transmitting an alarm to the remote location responsive thereto, when said movements of predetermined distance have been detected.

17. A global tracking system (GTS) for monitoring an alarm condition and locating a movable object, the GTS comprising:
-
a GPS (global positioning system) receiver located with the movable object, the GPS receiver being effective for providing data reflecting a present spatial position of the movable object, in terms of spatial latitude/longitude coordinates; means for noting an alarm condition by detecting movement of the movable object which exceeds a predetermined distance; and means for transmitting the occurrence of such movement wirelessly to a remote location in response to said alarm condition and when said movements of predetermined distance have been detected. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
