The invention discloses a high-precision micro-deformation attitude control instrument installing structure for a spaceflight. An instrument installing plate comprises a first wing plate, a second wing plate and a web plate. The first wing plate is fixed to the outer surface of a thin-wall shell structure. The second wing plate is arranged in the thin-wall shell structure and connected with a plane butt-joint flange of a heat conducting body. The first wing plate and the second wing plate are connected through the web plate and carry out heat exchange through the web plate. The installing face of the heat conducting body is connected to a sealing cover plate which is connected with the thin-wall shell structure to form a head of the installing structure. One end of a supporting rod assembly is connected with the head of the installing structure. The other end of the supporting rod assembly is installed on a body of an optical imaging effective load structure of the spaceflight. The technical problem of rigorous thermal deformation of the attitude control instrument installing structure is solved, the installing structure has an excellent heat transfer property and a thermal deformation isolation property, the requirement for high-precision attitude determination and image navigation rectification of the spaceflight is met, and the installing structure has the advantages of being novel in structural form, light in mass and the like.
