Abstract

The invention relates to a high-speed data communication method based on a minisatellite cluster ad-hoc network. According to the method, a hybrid network structure is adopted, a minisatellite cluster firstly adopts a centerless ad-hoc network structure, interaction of related information of networking operation control in the cluster is realized, and on the basis, services such routing, route building and control are provided for high-speed transmission of satellite sounding data in the cluster. The hybrid network structure combines advantages of a centerless structure and a centered structure, can realize high-speed transmission of the sounding data in the cluster under the conditions of different mission requirement and different formation configuration, and has a series of advantages of no center, self discovering, automatic configuration, self organization, fault self-recovery, self-adaptive formation changing, high reliability, high availability and the like of a wireless ad-hoc network.

Description

technical field

[0001] A high-speed data communication method based on a small satellite cluster ad hoc network of the present invention belongs to the technical field of satellite formation networking. Background technique

[0002] In the existing communication satellite constellation systems, such as Iridium and Global Star systems, the satellites are located in different orbital planes, forming a fixed constellation configuration, and the communication links between satellites are determined; while the small satellite formation systems, such as Techsat-21, TanDEM-X, GRACE, etc. also adopt a fixed formation configuration. These systems only establish fixed inter-satellite communication links, and do not have inter-satellite data exchange and multi-hop transmission capabilities. They are not enough to be called inter-satellite networks, let alone realize self-organization net.

[0003] The F6 system concept proposed by the United States, the system can operate independentl...
