Construction Method of Reconfigurable Satellite Information Network System Based on Special Nodes

To meet the design requirements of in orbit assembly spacecraft, this article proposes a method of reconstruction for the Spaceborne information network system for modular spacecraft in orbit assembly. The core of this method is to select a dedicated node on the SpaceWire routing chip as the information processing center for the link construction of functional module processing system. In order to handle the changes of system hardware structure, a series of dedicated link construction command set and specific execution logic are designed for system information network building. This method is also effective for in orbit module assembly and reconstruction of the modular satellites.
