The invention discloses a high-accuracy micro deformation star sensor mounting bracket. A star sensor mounting plate is connected to the outer surface of a thin-wall shell structure; a heat pipe is positioned inside the thin-wall shell structure; one end of the heat pipe is connected to the star sensor mounting plate; the other end of the heat pipe is connected with a heat collecting plate; the heat collecting plate is connected to the inner side of the top of the thin-wall shell structure and partially extends out of the top of the thin-wall shell structure; a first insulation mat is mounted between the heat collecting plate and the thin-wall shell structure; a rear cover board is connected to the back of the thin-wall shell structure so as to form a mounting bracket head; one end of a strut assembly is connected with the mounting bracket head; the other end of the strut assembly is used for mounting a spacecraft optical imaging effective load structure body. The high-accuracy micro deformation star sensor mounting bracket solves the technical difficult problem of harsh thermal deformation of a high-orbit spacecraft star sensor mounting bracket so as to meet the requirements on high-accuracy attitude determination of a spacecraft and image navigation registration, and meanwhile, has the advantages of novel structural form, light weight and the like.
