| Abstract: | Technical development of spaceflight and network communication make inter-satellite,satellite-ground networking into feasibility and reality.In this article,physical layer of the network is by the numbers investigated.In the space links,all kinds of factors that may affect propagation of electromagnetic wave are researched and summarized.Firstly the general factors are analyzed such as free space,atmosphere and ionosphere,secondly the especial factors are investigated such as antenna,space environment and enemy assault so that it can provide theoretical basis to ensure the reliability of space-terrestrial communication and validity of network management. |
