A ground-based, precision aircraft landing system provides CAT I precision approach and landing guidance. The aircraft elevation position is determined by measuring differential carrier phase and time-of-arrival of the aircraft ATCRBS transponder reply. The transponder reply is received at a plurality of sensor antenna locations where it is then conveyed to a sensor, demodulated and digitized. The data is transmitted to a central processor where calibration and multipath corrections are applied. Aircraft transponder diversity antenna switching is isolate...


1. A method of determining a position of an aircraft having a transponder which transmits a reply signal in response to an interrogation signal, the method comprising:receiving the reply signal on a plurality of antennas disposed as a vertically oriented array; estimating a position of the aircraft from the received reply signal; determining selected characteristics of the reply signal; and, analyzing the selected characteristics to determine whether selected reply signals originate from different antennas on the aircraft.
