Analysis and Design of the Communication System for Multi-Probes Joint Lunar Polar Exploration

Abstract

The communication system is one of the important subsystems of a lunar polar explorer. Because of the significant differences compared to the missions in lower latitudes，the features and requirements of communication design need to be clarified for lunar polar soft-landing explorations for the multi-spacecraft mission to explore the polar region of the Moon. In this paper，the communication system architecture，communication environment conditions and data volume and other mission requirements are analyzed，and the lunar polar area communication system link architecture is designed. The scheme is based on a set of lunar relay communication network. The link structure composed of the lunar communication network realizes the reliability and scalability of the system through the mutual backup of heterogeneous links and multi-center nodes，taking into account the optimal allocation of resources in the system. It can provide guidance for the implementation of future lunar polar region exploration and communication technology projects，as well as future lunar polar region exploration and communication technology projects.
