When the multi-rotor aircraft is flying, the multi-rotor player may need to immediately know the images shot by the equipped camera due to immersive photography enthusiasm, the view angle control, deep disaster searching, mission staff safety consideration or exhaustive survey for disaster damage area and FPV (First Person View) equipment become an indispensable tool. FPV equipment is used to control the multi-rotor from the pilot's view point no matter how the rotorcraft is far from the player and located in the complex environment by providing the player instant image of flying, the rotorcraft accurate position, attitude, or other information. It let photography enthusiasts to instantly realize their amazing ideas by control the shooting view angle of camera. It also can be used to search any dangerous regions for the military mission in rescuing in the disaster areas. However if the instant received images from FPV are required to be clear and stable, a dynamic tracking antenna is essential equipment that can be always aligned with multi-rotor aircraft. It can allow for more flight distance farther, more attractive shooting images, and more instant flying data monitoring. In this study, we develop a tracking system that is made up of a plane antenna attached with 2 motors and an Arduino board. The Arduino board receives the multi-rotor’s GPS information from ground station, calculates the angles of bearing and elevation, and drives the motors to rotate the high-gain antenna to point to multi-rotor aircraft. The experiment result shows that the rotorcraft flight distance can be increased, the dynamic rotorcraft flight data can be instantly and effectively transmitted and received, and the real-time video and images can be more attractive. The result can be contributed to the military for carrying out disaster rescuing mission.
