Abstract

The invention provides an integrated mounting bracket for star sensors. The mounting bracket comprises a mounting bottom plate, an overall support platform, a plurality of support barrels and mounting flanges, wherein the mounting bottom plate is fixedly connected with a satellite platform; the overall support platform is fixedly connected with the mounting bottom plate; the plurality of support barrels are connected with the overall support platform respectively; the mounting flanges are arranged at the top ends of the support tubes and used for mounting the star sensors. According to the integrated mounting bracket for the star sensors, integrated mounting of three star sensors is realized according to a satellite attitude and orbit control subsystem scheme and the mounting requirements of the star sensors, and conditions of non-uniform bracket forms, complicated design and processing procedures and longer period occurring when the star sensors are separately mounted are avoided.

Description

technical field [0001] The invention belongs to the field of aerospace technology and satellite equipment, in particular to an integrated mounting bracket for a star sensor. Background technique [0002] When a satellite is in orbit, it is usually necessary to determine the attitude of the satellite coordinate system relative to a certain reference coordinate system or a specific target, and obtain the attitude information for use by the on-board control system, payload, and ground measurement and control system. In order to determine the attitude information, it is necessary to use the attitude sensor on the star to obtain the physical quantity containing the attitude information, and then perform data processing on it to obtain the attitude data. Among them, the commonly used star sensor is sensitive to imaging the light direction field of the star. Since the angle of view of the star is very small, and the orientation of the star in space is very accurate based on the res...
