Abstract

In recent years, JAXA has been conducting a technical survey for a geostationary Earth observation satellite using a 3.5 m diameter aperture with a segmented primary mirror. One of the problems associated with such a large optical observing satellite is a reduction in image quality due to thermal deformation of the optical elements and the metering structure. In this paper, we present our first conceptual structural design and thermal analysis of that design. We also propose a solar light incident avoidance maneuver for this satellite and show the validity of that maneuver.
