Abstract: This paper studies the connectivity of satellite communication links for the maritime long-distance sailing ships. On the basis of theoretical analysis of satellite communication system composition, antenna and channel models, based on the STK/Comm communication analysis modules, software-integrated transmitter and receiver models, atmospheric absorption models and rain attenuation models, this paper completes the setting of the link parameters, builds a satellite communication link simulation environment including inter-satellite links, uses the software dynamic processing capability to complete the three-dimensional situational visualization display, and generates the detailed maritime satellite communication multi-hop link performance reports. And the possible existing interference is analyzed to provide an important reference for the design of maritime satellite communication links.
Keywords: multi-hop communication link; visualization simulation; STK
