Maritime antennas provide communication between ships and satellites. However, unlike terrestrial ground stations, the dynamic environment of the ocean affects the directionality of maritime antennas, leading to signal attenuation and communication interruptions. To address these challenges, this study aims to optimize the algorithm development of the Antenna Control Unit (ACU) for maritime antennas. The goal is to compensate for the attitude changes caused by sea movements and ensure that the azimuth, elevation, and roll angles conform to the antenna′s mechanical settings, achieving more efficient and precise tracking.
The algorithm is written in C language due to its high efficiency, portability, and ability to handle real-time computational demands. Although this study has certain limitations, future work can involve testing the results in actual sea conditions to validate the practical application of the research outcomes. Additionally, the algorithm and control methods can be optimized for different types and scenarios. |
