Abstract: A global positioning and tracking system for locating objects including a plurality of tracking devices each releasably secured to an object and a central monitoring station. Each tracking device includes a processing device for storing an identification code unique to the tracking device, determining a location of the tracking device and generating a position signal based upon the determined location, a cellular transmitter/receiver for receiving and initiating cellular transmissions. The central monitoring station receives a location request and identification code from a user and initiates a cellular transmission including the identification code to a telephone number assigned to the tracking units. Upon receipt of the cellular transmission each tracking unit compares the identification code with its stored identification code.

Abstract: A personal locator system for determining the location of a locator unit. The system includes a locator device in communication with both a central station and a GPS satellite. The locator unit includes a portable housing able to be worn about the wrist of a user. A communication system is positioned within the housing for contacting the central station and includes a transmitter and receiver. A GPS unit is also positioned within the housing for contacting the GPS system for determining a location of said locator device. Upon receipt of a location request signal by the receiver from the central station, the locator unit activates the GPS unit to contact the GPS system and receive location data therefrom. Upon receipt of the location data, the transmitter transmits the location data to the central station for analysis. A panic button is provided for transmitting an emergency signal to the central station and initiating detecting the location of the locator unit.

Abstract: A global positioning and tracking system for locating one of a person and item of property. The global positioning and tracking system comprises at least one tracking device for connection to the one of the person and item of property including a processing device for determining a location of the tracking device and generating a position signal and a transmitter for transmitting said position signal. The position signal is transmitted to a relay station strategically positioned about a desired monitoring area. The relay station includes a device for receiving the positional signal and determining if the received position signal is a valid signal and a device for relaying the position signal upon determining the position signal is valid to a central monitoring station. The central monitoring station receives the validated positional signal from the relay station and analyzes the position signal for monitoring the position of the tracking device.
