Antenna Registration Question 4: Directional Antenna Information An auto-tracking antenna has been designed specifically for use with the EnerLinksIII system and is a highly integrated solution. The assembly is a combination of a high gain directional dish, a low gain omni-directional antenna and associated auto-tracking hardware: - The antenna system includes an omni antenna for close-in operation of the aircraft, such as for take off and landing, where the angular velocity of the aircraft relative to the antenna is too great to track, and a high gain directional dish for long range operations. - The auto-tracking antenna is provided with the GPS position of the aircraft. Tracking is accomplished using a combination of GPS and signal strength. Signal strength is used to find the aircraft when the tracking is not locked, and GPS is used to follow it thereafter. - The parabolic reflector used in the auto-tracking antenna has a diameter of about 2 feet (approx. 60 cm).and has gain of about 28 dBi at C-band. Antenna beam width is about 5 degrees. (see Figure 1) Figure 1: Autotracking antenna assembly.
