Dynamic interaction in precision pointing systems - Analysis and test methods
Abstract
The demand for precision pointing of optical instruments on space platforms has been increasing over the years. These instruments must operate in adverse dynamic environments while maintaining the pointing accuracy and stability. This paper discusses one such application where extensive analysis and verification tests at various levels of hardware production and build-up were performed to understand and minimize the interaction of moving elements with the optical instruments' line of sight. Specific analysis techniques used and test program undertaken are a highlighted and representative results are presented. It is shown that as a result of these analyses and test program, required design modifications were implemented early in the program avoiding expensive and time consuming rework at later stages.
