Optimizing design decision-making for remote sensing instrument specification via tolerance sensitivity analysis of Ritchey–Chrétien telescope

Abstract

The objective of thisstudy was to assess the tolerance sensitivity of various aperture sizes in the Ritchey–Chrétien telescope employed in remote sensing instruments. A comparative analysis was performed to identify the optimal system specification considering different aperture sizes and marginal tolerances. The results were then utilized in the Formosat– 8 satellite program to determine the most suitable aperture size for fabricating the mirror components and establish the tolerances budget for the system alignment of the Formosat–8 satellite remote sensing instrument.
