The low-
inertia optical
satellite configuration comprises a
satellite body, a camera and a solar wing, the
satellite body is of a
hexagonal prism structure, the two axial end faces of the
hexagonal prism structure are the ground facing face and the
sky facing face respectively, the interior of the satellite body is divided into a platform cabin and a load cabin through a middle partition plate, and the platform cabin is arranged close to the
sky facing face; the load cabin is arranged close to the ground; one part of the camera is mounted on a middle partition plate of the load cabin, and the other part of the camera extends out of the ground; the two opposite side faces of the satellite body are solar wing installation faces, solar wings are installed on the solar wing installation faces, and the solar wings are unfolded in the direction perpendicular to the central axis of the
hexagonal prism structure after being unlocked and opened from the solar wing installation faces where the solar wings are located. According to the low-
inertia optical satellite configuration, the camera is installed in the load cabin and half sinks in the satellite cabin, the solar wings of the satellite body are symmetrically arranged on the two opposite sides of the satellite body in a two-dimensional unfolding mode, and by means of the configuration, the rotational
inertia of the satellite in
orbit can be reduced.
