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. A non-emergency call button is provided for transmitting a location request signal to the central station and in response thereto, informing a person on the contact list as to the location of the locator device. The communication system utilizes one of a POTS, cellular, PCS or internet communications network. A tamper detection sensor detects when said device is tampered with. A beacon generator generates an ultrasonic or radio frequency beacon signal for aiding a person in pinpointing a location of the device.
