Research of Stable Tracking System for the Directional Antenna of UAV

The key problem to keep UAV work safely and efficiently is that the directional antenna can track the flight direction of UAV steadily.This paper proposes a preliminary design scheme of antenna stable tracking system,describes its operational principle,and then discusses antenna direction according to GPS positions,control method and accuracy of the tracking system.The structure of the system is simple and inexpensive,and it is applied for different ground control stations.
