Paper Abstract

Future flight projects at JPL such as the Large Deployable Reflector (LDR) require close design effort between controls, dynamics, structures, optics, and thermal disciplines. The Figure Control Simulation (FCSim) program has been developed under the Precision Segmented Reflector (PSR) program of NASA to perform analysis on a particular moderate mission of interest, a telescope with a 3.65 m primary mirror broken into 7 segments, designed for 100 - 800 micrometers wavelengths. Simulation code is designed to handle both the flight system and a ground-based test system. The optical analysis, performed using the Controlled Optics Modeling Package (COMP) can handle multi-spectral images, extended sources, image smear due to jitter of the structure, and surface irregularities of the panels. Various dynamic disturbances are included as well. One simple method of aligning the panels is presented. Results obtained with FCSim are presented.
