Abstract: | A new approach to Air Traffic Control (ATC) calls for every aircraft to periodically broadcast its GPS de- rived position. The position reports are to be received by ground baaed controllers and by other aircraft in the vicinity of the transmitter. This technique can in- crease the quality and extent of ATC surveillance cov- erage, and provide a highly accurate Traffic alert and Collision Avoidance System (TCAS) for all aviation. The key to the successful application of this concept is a proper design of the communication channel. This research identifies the basic parameters that govern the channel capacity, and sets bounds on the performance of several Time Division Multiple Access (TDMA) pro- tocols. The maximum improvement that can be ob- tained by using a self organized protocol is studied by using a Monte Carlo simulation of random air traffic. |
