- Abstract
Interplanetary missions will require the Deep Space Network (DSN) to establish the communication link between the spacecraft and the ground station. In the realization of IDSN 32 meter antenna with Beam Wave Guide (BWG) system, multiple reflective mirrors has been chosen for minimum loss RF energy interaction between satellite and ground station feed systems. It consists of a series of flat and doubly curved mirrors arranged to propagate the RF energy in desired direction. Since these mirrors are highly directional, the orientation and positioning of each mirror to an accuracy of milli degree and sub millimeter respectively, is expected in 3D space. A shroud system with mirror adopters have been designed and developed to achieve the required mechanical accuracies. Support fixtures and adjustment mechanisms have been designed for stationary mirrors and feed systems to achieve positioning accuracies. This paper addresses software and hardware tools developed for mechanical design, structural analysis, and alignment techniques for the Beam Wave Guide system for achieving optimum RF performance.
