ABSTRACT:
A compact, reliable, paraboloid shaped assembly 7 is used as a reflector 7 on a satellite. The apparatus 7 is assembled from multiple panels 2, 3, 4, which connect to a central base 1 using hinges 20, 21. The apparatus 7 is compacted by rotating some or all of the panels 2, 3, 4 to be adjacent to one side 12 of the central base in stages, such that alternate panels 3 are rotated first. Folded onto these panels 3 are the remaining backwards-folding panels 2. The panels 4 which are not rotated backwards are then rotated forwards, completing a highly compact design. For deployment, the panels 2, 3, 4 are rotated in the reverse order and direction in which they were compacted. Latches 10 connect adjacent panels 2, 3, 4 and hold the panels 2, 3, 4 in the deployed position.
