and equipment. The construction fixture is a rugged heavy gage metal structure upon which all of the elements of the construction base are mounted. The fixture constitutes the reference surfaces for the construction operations and the locating jig for the equipment which either constructs or installs various elements of the satellite. The location of the major construction equipment is shown on the figure. Thirty-three tri-beam fabricators, installed at thirteen different locations as indicated by 7A and 7B are required. Dispensing devices for the solar blankets, reflectors, solar array retention cables, and power distribution conductors 9 and 10 are located at the bottom and sides of each of the three troughs. The assembly facility for construction of the microwave antenna frame, denoted by 6A, including its tri-beam fabricators 6D is located in the center of the SCB. Also shown is the RF elements assembly and installation facility, 6B which translates towards the completed antenna frame and provides a platform from which the RF elements are attached to the antenna as it translates past the platform in guideways 6C. Facilities for docking I0TV's and for storing cargo are provided on the platform 4 located to the left of the antenna fixture in Figure R-28. GEO construction base support facilities and their locations also are identified in Figure R-28. A crew size requirement of 680 has been estimated for accomplishing the construction in the scheduled time. The crew and their facilities are divided equally and are located on each side of the hex portion of the fixture as shown. One of these 340 men facilities shown in more detail in Figure R-29, consists of 7 three-module crew habitability complexes plus 2 base management modules, 2 pressurized storage modules and solar array power modules. The modules of the crew habitability complex are described in more detail in the lower right of the figure. Each complex is composed of two of the crew hab modules, each of which provide staterooms, personal hygiene facilities and support subsystems for 24 crewmembers; and one crew support module which provides galley, recreational and medical facilities and subsystems for the 48 crewmembers of the two crew hab modules.
