Central structure

Made of a Carbon Fibre Reinforced Plastic (CFRP) sandwich construction cone. The cone features bonded aluminium alloy upper and lower rings.

Box structure

Around the CFRP cone are upper and lower floors and external walls, forming a rectangle with shear walls that link the central cone to the external rectangular box structure. All these elements are made of aluminium alloy sandwich panels.

Battery compartment

This includes the assembly of the battery support plate and five equi-spaced radial stiffeners.

Flat Solar Array Drive Mechanism (SADM) mounting structure

A set of local support structures (brackets and panels) for Attitude and Orbit Control Subsystem (AOCS) sensors and actuators, harness and antennas.
