Abstract

With the development of the new generation of broadband satellite communication systems, which represented by satellite internet, exhibit the demand for flexible switching of access and feeder links to save onboard beam resources, as well as the demand for special users to access onboard payloads through dedicated channels. To meet these demands, the paper proposes a multibeam access link and feeder link integrated spaceborne communication system. This article conducts three integrated designs: the integrated design of the system protocol, the integrated design of the onboard antenna, and the integrated design of the onboard processor. It also describes two key processes: beam mode switching and data diversion of the onboard gNB (Next generation node B). The designed communication system has three advantages. Firstly, it achieves dynamic multiplexing of satellite beam resources. Secondly, it achieves efficient utilization of onboard equipment. And thirdly, it achieves flexible and secure networking for specific types of users.
