Abstract
A four element antenna turnstile tracking system which outputs an azimuth error signal, an elevation error signal and an independent sum signal. Three tracking antennas are disposed triangularly at the vertices of a triangle and the sum antenna is disposed in a predetermined relationship to the tracking antennas. The three tracking antennas are symmetrically connected to a unique four port turnstile type junction which generates an elliptical wave in accordance with the difference in signals from the three tracking antennas. An orthogonal mode transducer outputs the orthogonal components of this elliptical wave, these components being the azimuth error and the elevation error signals.
