Local transportation equipment is also divided into several categories and is described in subsection 12. 2. 6. The cargo docking and storage areas and vehicle refueling stations were sized from logistics models as described in subsection 9. 2. Manpower for SPS manufacturing and construction is shown in Figure 9-12. 9. 3. 4 TERMINAL FACILITY Because of the large amount of supplies involved, a terminal facility or depot must be provided to store and centralize many of the materials used for construction of the SPS. This facility would be capable of storing tanks of propellants, lubricants, cryogenics and other fluids, beams, solar blankets and reflectors, spare OTV engines, etc. Docking ports would be provided on the facility to accommodate both shuttle and tug vehicles. The depot would also be equipped with cranes, manipulator arms, elevators, rail systems, etc., for storage and retrieval of supplies and materials. No attitude control system is needed for the depot, since it is attached to the space station. Table 9-4 shows the capacities of the various depot departments for both LEO and GEO facilities.
