The invention provides an in-orbit expansion-type satellite structure which comprises a plurality of satellite body modules with the same configuration arranged along circumference, wherein the adjacent satellite body modules are connected by an expansion-type truss, and a corresponding satellite body connecting and unlocking device is disposed between the adjacent satellite body modules; at a launch stage, the satellite body modules are connected by the satellite body connecting and unlocking device into a whole, so a satellite body is retracted and satisfies a demand for carrying and enveloping during the launch; when the satellite body enters an orbit, the satellite body connecting and unlocking device works to realize unlocking among the satellite body modules, and the satellite body modules realize in-orbit expansion under effect of the expansion-type truss; and during in-orbit work, in-orbit high-rigidity locking of the expansion-type truss is realized by a locking mechanism of the expansion-type truss. The in-orbit expansion-type satellite structure provided by the invention solves the contradiction between that the satellite body cannot exceed a carrying limit and that the satellite shall satisfy a structural configuration demanded by an in-orbit large load, and provides an engineering solution manner for subsequent applications of the large load.
