Embodiment
Just by reference to the accompanying drawings the present invention is described further below.
Of the present invention based in the separation module Space Vehicle System of state aware, each separation module spacecraft is independently module spacecraft, can injection executing the task separately.In the process of executing the task, variant module spacecraft by forming cluster network alternately, thus forms the system in-orbit existed with cluster network form.
For realizing the networking function of cluster network, each module spacecraft is all configured for the communications component of cyber-net in-orbit of networking.Wherein, it is mutual that network communication components is responsible between module spacecraft, i.e. the transmitting-receiving of network communication data and instruction; Computer interactive output control network state in-orbit, is specially network state management and the network communication data process of this module spacecraft responsible.
As Fig. 1, each module spacecraft in cluster network can be in different network states respectively, and this network state comprises: isolated node state, primary node status, from node state, candidate primary node status and communication fault state.Corresponding to different network states, the node of each module spacecraft all as network in cluster network, and can being defined as respectively according to residing network state: isolated node, host node, from node, candidate host node and communication failure node.
