The invention provides a satellite propulsion service cabin structure which is suitable for a satellite structure family system with large bearing and multi-load adaptive capacity requirements. According to the cabin structure, a main force bearing structure is composed of a satellite-rocket butt joint ring and beam-slab composite structural slabs, the beam-slab composite structural slabs form three sets of W-shaped plane truss units, and in a top view, the three sets of planes intersect at the central axis and are distributed in a star shape. According to the cabin structure, the four large spaces divided by the star-shaped truss are used for installing the storage tank, the lower portion of the storage tank is directly connected with the butt joint ring, the upper portion of the storagetank is connected with the truss joint through the pull rod, and the structural weight is greatly reduced through the storage tank connecting mode. The two smaller spaces of the invention allow to beused to mount gas cylinders. By means of the structure, the large bearing capacity of the propelling service cabin is ensured.
