| Abstract: | The aperture of optical remote sensor is larger and larger for the increasing resolution and the development of geostationary earth observation.Large aperture reflector has become a key factor affecting the performance,weight and cost of the remote sensor.The ultra-light reflector with 2m diameter is studied and the function of positioning and mounting system is analyzed.The positioning and mounting scheme which fit the large aperture ultra-light reflector is put forward and the realization of the scheme is given. |
