A deployable perimeter truss reflector is capable of achieving a hitherto unobtainable thirty to one ratio in size between its size in the deployed condition and the stowed condition. The improved truss reflector structure is characterized by deployable spars that are attached to and extend from a basic frame structure to the truss. When deployed the spars are positioned outwardly and away from the basic frame of the truss, carrying the catenaries, and, the latter carrying the reflective surface into position at an end of the truss cylindrical truss. New catenary systems, deployment mechanisms, basic truss structures and cable management systems are also described.
