description An instrument landing system (ILS) having distributed localizer receiving antennas and localizer signal information processing to provide a composite guidance signal having reduced localizer beam noise for reduced lateral touchdown dispersion in automatic landing systems. A plurality of conventional localizer antennas are positioned at several laterally displaced points across the approach path along the wings of an aircraft and the corresponding plurality of received localizer beam deviation signals received by each of these antennas is individually processed by a localizer receiver system with the audio course deviation signals developed from the several antennas being averaged to provide the composite guidance signal for use in autopilot or crosspointer indicator.
