LEO antenna ground station analysis using fast fourier transform

Abstract

One of the quality requirements of a satellite low Earth orbit receiver antenna that maintain is pointing accuracy. The research is trying to using FFT to analyze the quality of the LEO satellite receiver antenna. Currently, the antenna tracking error analysis using graphs fault elevation and azimuth error compare to the time. This study is conducted find the effectiveness of the frequency and amplitude of the tracking error using (FFT). FFT is able to count the amplitude and frequency error. Calculation and plotting error by FFT in this study shows amplitude and frequency error. The goal system malfunction at data reception, recording satellite reception can be detected earlier. Solution and problem solving more efficient, availability of systems also data continuity can be maintained and protected.
