Research of Reconfiguration Technology for Spacecraft Cluster Control system Based on Wireless Network

Spacecraft cluster is constituted by a large number of member spacecraft which are autonomously and cooperatively executing on-orbit tasks. In this paper, a spacecraft cluster control system based on Zigbee is designed. Wireless network communication is adopted not only among all member spacecraft, but also within each spacecraft, replacing the traditional wired connection. The system reconfiguration concept, network secure access protocol, and control system reconfiguration protocol are designed to ensure system security and reconfiguration ability. The experimental systems, which consist of wireless nodes and spacecraft component elec-simulators, are constructed to verify the feasibility of the proposed system scheme.
