Antenna pointing control for satellite tracking systems with perturbations - Case of assuming for small ship

We propose an antenna control system with high response and high accuracy, implemented using a simple reliable mechanism with a three-axis attitude sensor and AGC sensor. The AGC level represents the strength of the received electric waves. In this research, we use an actively controlled two-axis gi...

Summary:We propose an antenna control system with high response and high accuracy, implemented using a simple reliable mechanism with a three-axis attitude sensor and AGC sensor. The AGC level represents the strength of the received electric waves. In this research, we use an actively controlled two-axis gimbal structure that provides control of azimuth and elevation, and a three-axis vibratory gyroscope for the attitude sensor. The three-axis attitude sensor has the advantage of quick movement and can produce high resolution, but has low accuracy due to drift after enough time. The AGC sensor can produce the absolute position not depending on time, but has low resolution. We improve the tracking performance of the existing antenna system by using both the merits of the AGC history and the base attitude measured with the three-axis sensor. (Author)
