A system and method are provided for communicating between a person, object, and/or vehicle carried transceiver and a monitor station to locate and track the movement of the same for security or anti-crime purposes. A portable computing and communication device carried by a person or located (hidden) in an object generates and transmits via radio signals a plurality of codes when remotely activated. One (or more) code(s), identifying or descriptive of the person, object or vehicle to be tracked, is (are) generated and transmitted to a monitor station to display character and/or video picture information describing and/or physically displaying a picture of a select person and/or vehicle and license plate information to permit police or security personnel to recognize the same. Such coded information may be immediately transmitted or retransmitted from the monitor station to a radio receiver carried by a policeman or in one or more police vehicles. The portable device is equipped with location sensing capability, such as receiving signals from satellites such as from the GPS constellation, and a computer for calculating its position using triangulation methods. Transmission of the position signals from the portable device is inhibited for a time by entering thereat an inhibit personal identification number (PIN). Further, PINs are used by the monitoring station to activate and/or override the inhibiting feature.

[ What is claimed is:] [1.] A method for locating one of a plurality of identifiable, moveable objects on the surface of the earth comprising:(a) receiving location-indicating information signals from a plurality of earth satellites at a portable receiver coupled to a moveable object;(b) calculating the location of said object using said location-indicating signals;(c) transmitting a remotely generated inquiry signal particularly identifying the object;(d) when the receiver of the object receives the inquiry signal, transmitting from said receiver to a monitor station signals indicating the calculated location of the object; and(e) employing said transmitted signals to intelligibly indicate at the monitor station the location of said object;(f) wherein the transmission of calculated location signals from the object is inhibited for a time by entering an inhibiting personal identification number at the object.
