Abstract
The influence of jitter on the interface between space camera and satellite platform may cause the camera structural distortion, which will change ideal assembly and adjustment relationship of optical system, and affect the imaging quality. An integrated model of a high resolution space camera comprising reaction wheel assemblies disturbance which induced the largest jitter of spacecraft, structures and optics systems was developed in order to predict the expected dynamic performance of the camera in terms of MTF descending and image motion. The process as currently implemented uses Pro/Engineer for design, PATRAN and Hypermesh for model building and results visualization, NASTRAN for structural analysis, and Code V for optical analysis. A translator was developed in MATLAB to transfer PATRAN results to Code V optical analysis software. This jitter analysis results are used to assess image quality, improve the structural design, and mitigate the disturbance impact.
