Abstract: A satellite based air traffic control (ATC) system includes an aircraft unit on an aircraft and an ATC facility. The aircraft unit includes an AARTS processor, GPS receivers or other satellite receivers, a comparator for comparing the GPS data, a two-way radio, and a transmitter and receiver for communicating information and data over a data link with the ATC facility. The ATC facility includes an ATC computer, a two-way radio, a display for displaying aircraft, and a transmitter and receiver for communicating information and data over the data link. The aircraft transmits aircraft identification information, GPS data, aircraft status information, and a transmit detect code to the ATC facility to allow the ATC to track the aircraft and identify the aircraft communicating on two-way radio. The traffic control system and a flight control system utilizing GPS may be used for aircraft in the air and on the ground, and may be used for ships, boats, automobiles, trains or railroads, and aircraft.
Abstract: An apparatus and method of tracking and reporting the location of a mobile article, such as a stolen motor vehicle. A controller receives and analyzes positioning signals transmitted from known locations to determine the location of the motor vehicle. The controller contacts a central tracking station to report the theft and the location of the motor vehicle.
Abstract: An apparatus and method for notifying a party of a pending delivery or pickup of an item. A mobile vehicle or carrier is equipped with a satellite receiver, a controller and a communicator. The mobile vehicle determines its location based on positioning signals received by the satellite receiver. The controller compares the current location of the vehicle to the location of the party receiving the delivery/pickup. The communicator conditionally communicates with the party to notify the party of the pending delivery/pickup.
