Abstract
In satellite laser communication, the ability of communication terminals to continuously track a beacon light is crucial for maintaining communication link stability. The primary factor affecting real-time tracking is vibration of satellite platform. A neural-network-based prediction approach for beacon light positioning is introduced to mitigate the impact of vibrations on tracking accuracy. Experiments were conducted to verify the proposed approach. Compared to traditional moving average model predictions, the prediction accuracy results improved by more than 50 % with random vibrations, particularly in the mid- and low-frequency domains. This novel approach provides valuable insights for enhancing the accuracy of beacon light tracking.
期刊介绍:
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
