Satellite terminals utilize a tracking technique based on the terminals' characteristics. A recent challenging issue is determining the technique for an unmanned aerial vehicle (UAV) terminal because it has a small space for installation. The unmanned characteristics lead system engineers to implement redundant satellite-tracking techniques for stable tracking. To satisfy these issues, this paper proposes step-tracking and multimode-monopulse techniques considering UAV characteristics and analyzes their tracking accuracy. Finally, by using a Ku-band satellite, the test results for the tracking accuracy of both techniques are presented under UAV flight conditions.
