A satellite (10) has two solar array panels (40,42) which are moveable between a closed configuration and an open configuration. The solar array panels are pivotably mounted on hinges (44,46) attached along the top and bottom of the satellite and extend outwardly from the top and bottom of the satellite in the open configuration. The height of the perimeter sidewall (14) is selected such that the satellite has a generally oblate configuration. Each solar array panel has a surface area substantially equal to that of the satellite cross-sectional area. The hinges (44,46) are mounted on pintles (48,50) extending from a solar array drive motor (58) which rotates the solar panel about the axis defined by the pintles to provide one axis sun tracking. The solar array panels are pivoted about the axes of the hinges until substantially parallel to the top and bottom of the satellite to form a compact, stackable configuration of the satellite for stowage. Three couplers (54A,54B,54C) positioned along the perimeter wall couple the satellite to similarly configured satellites within the fairing of a launch vehicle. The coupled satellites form a stack having three load-bearing columns consisting of the satellite couplers. In the stacked configuration, the couplers of one satellite are attached to the couplers of adjacent satellites by bolts restrained within non-explosive separation nuts (106). Pre-loaded compression springs (144A,144B) extend between the couplers of adjacent satellites. After the stack of satellites separates from the fairing (52), each satellite is successively deployed from the stack, starting with the top-most satellite. Deployment begins by activating the non-explosive separation nuts (106) in the couplers of the top-most satellite. Thereafter, the pre-loaded compression springs (144A,144B) extending between the coupling devices of the top-most satellite and the subjacent satellite (or, for the bottom-most satellite, the subjacent booster stage) accelerate the top-most satellite away from the stack and booster stage.
