A locator system for locating a person, animal or mobile object for use with a cellular network, the locator system including a fob containing a GSM transceiver for communication with the cellular network, a GPS unit for indicating the location of a person, animal or object being searched for, a baseband processor for controlling electronic modules in the fob and an RF beacon for transmitting strong ID signals in pulse form for indicating the direction and location of the fob. The system can operate with a call center to which communications are made by a guardian seeking assistance in finding the lost person, animal or object, which in turn communicates with the cellular network to send signals to activate the fob and which receive signals from the fob. Mobile or handheld tracking units pick up GPS and RF beacon signals to find the fob. The locator system can be used in combination with a residential locating system.
