The large size of the SPS requires a high degree of automation to achieve the necessary construction rates. The construction crew can be best utilized in servicing and maintaining automated equipment, evaluating the operation and output, and performing contingency operations. The construction and support crew operate a construction base consisting of construction and manufacturing facilities, orbital construction and support equipment, logistic facilities, integration management facilities, and crew habitability facilities. A conceptual GEO construction sequence for the column/cable perpendicular-to-the-orbital-plane (POP) configuration is shown in figure V-2. The schedule is phased for completion in 1 year. The construction facilities are assumed to be operational. Construction facilities are provided at each end of the major columns (fig. V-3). These facilities move out from the center of the SPS by generating structural members. Stabilizing cables are attached and deployed as the columns are extended. Packages of solar cell blankets and reflectors are attached to the column and connected to the power distribution system by construction personnel. Deployment of the collector is gradual as the column length increases (fig. V-4). Deployment is aided and monitored by personnel. Figure V-2.- Typical SPS construction sequence - column/cable (POP).
