Abstract:Inter-satellite laser communication has become a development boom nowadays, and inter-satellite links are easily affected by the vibration of the external environment or the satellite body, resulting in damage to the communication quality. In the field of satellite orbit modeling and visualization, traditional solutions rarely introduce the influence of satellite platform vibration on the link, which cannot meet the needs of future star network simulation. In order to reflect the influence of platform vibration during inter-satellite link communication, an inter-satellite laser link state model is proposed, which mainly studies the main parameters such as geocentric angle, laser power and platform vibration. The calculation accuracy and functional effectiveness of the inter-satellite visibility method are verified by experiments, and the error comparison and verification of the azimuth angle, elevation angle and inter-star distance are respectively. The error of azimuth angle and elevation angle is controlled within 30 μrad, and the error of inter-satellite distance is controlled within 110m. Through vibration superposition experiment, the degree of satellite platform vibration interference to link is verified, and the real situation of inter-satellite link is well restored.
