The invention provides a modular
satellite structure based on an
open type grid framework and a final
assembly method thereof, and belongs to the technical field of
satellite structures. The problems that according to an existing method, the defects of blind operation and
adhesive fixation are not fundamentally eliminated, the cable laying efficiency is low, and the weight of an outer plate is too large are solved. The
thermal control protection structure comprises an
open type main bearing grid framework and a plurality of
thermal control protection outer plates, the
open type main force bearing grid framework is a hexahedral cage-shaped framework formed by connecting six plate-shaped grid frameworks in a
butt joint mode. The
thermal control protection outer plates are arranged on at least one outer side face of the open type main force bearing grid framework. The plate-shaped grid frame is used for installing one side plane of the thermal control protection outer plate, and a force bearing structure of the plate-shaped grid frame is recessed inwards. The method is mainly used in the
aerospace field.
