Infrared earth sensor integrated mounting bracket

Abstract

The invention discloses an infrared earth sensor integrated mounting bracket. The bracket comprises a base plate, a shell, a support plate and flanges; the base plate is fixedly connected with a satellite platform, the shell for supporting infrared earth sensors is installed on the base plate, and the support plate for reinforcing the structure is arranged in the shell and divides the interior ofthe shell into two cavities. The infrared earth sensors are installed in the two cavities separately, and the flanges for mounting the infrared earth sensors are installed on the shell. Through the cooperation among the base plate, the shell, the support plate and the flanges, the simultaneous installation of multiple infrared earth sensors in the effective area on a satellite is achieved, the mechanical properties of the whole support are optimized, the defects that too many effective installation areas on the satellite are occupied in traditional installation methods are made up, and the problem is overcome that a relative relationship change occurs because separate mounting of the bracket causes deformation of infrared earth sensors due to a force and a thermal environment.

Description

technical field [0001] The invention relates to an integrated mounting bracket for an infrared earth sensor, which is especially suitable for the equipment layout equipped with two infrared earth sensors in a limited space of a satellite, and belongs to the technical field of the assembly structure of an infrared earth sensor for a spacecraft. Background technique [0002] The orientation of the spacecraft relative to the earth is very important for communication satellites, weather satellites, earth resource satellites and navigation satellites, etc. For three-axis stabilized satellites, if the satellite attitude is oriented to the ground, two infrared earth sensors can be used to cooperate to determine the two attitude angle information of pitch and roll, which further improves the accuracy of attitude determination. [0003] In the prior art, the traditional installation method of the infrared earth sensor on the satellite is: according to the installation angle of the in...
