Abstract

According to the requirements of satellite-terrestrial network communication for large manned spacecraft, an integrated satellite-terrestrial network structure suitable for manned spacecraft was proposed, and the network protocol was designed, which realized the expansibility of multi-cabin manned spacecraft network communication and the support of ground protocol. At the same time, the data security requirements under this network architecture are analyzed, and the methods of external attack protection and increasing the internal security of the network are designed. The virtual channel is used to allocate a single virtual channel to the network data link, which improves the security and reliability of the network. Finally, the correctness and validity of the design are verified by the flight of the Tianhe core module in orbit. The design can provide reference for the future network communication design of manned lunar landing and deep space exploration.
