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.
