Two-dimensional variation of the effective area (left column) and the illuminated area (right) for our proposed geometries (each detector is 60 cm × 60 cm). Top row: flat detector, zenith-facing. Second row: two detectors on two neighboring satellite surfaces. Third row: two detectors on opposite sides and zenith. Fourth row: four detectors on each side of the satellite, none toward zenith; Earth’s shadow is included. Fifth row: five detectors, one on each side and one zenith-facing. Bottom row: Zenith-facing cube with 30 cm height; shadow included.
