Abstract: An elevation measuring device for an air navigation system which includes a ground beacon using a commutated array transmitting successively from one radiator element at a time. One element of said array acts as a commutating cycle beginning marker and as a phase and amplitude reference. The airborne receiver imposes a programmed amplitude and phase modulation on successive sets of received pulses to simulate a scanning beam and effects a comparison of measured absolute values from pulse set to pulse set to produce elevation angle information. The first such set represents a first fraction (first half for example) of the array elements and the second set represents the remaining array elements.
