Low Energy Consumption Routing Path for Space Ad Hoc Network of Spacecraft Cluster

Abstract

Spacecraft cluster is a space system constructed by a certain number of modular spacecraft where information interaction and collaborative control can be realized through space wireless ad hoc network, so as to flexibly, efficiently and self-organized realize the combination, coordination and upgrading of various space capabilities. This will be one of the important development directions of space system. It is of great significance to use miniaturized and intelligent spacecraft to build spacecraft cluster, which can effectively reduce the construction cost of space system. In order to meet the requirement of low energy consumption for small spacecraft, this paper proposes a low energy consumption routing method for spacecraft cluster. Based on the analysis of wireless communication model and spacecraft relative motion equation, the low-energy routing path construction method of spacecraft cluster wireless ad hoc network is studied by using graph theory method, and the spacecraft cluster is simulated under various initial conditions.
