轻型高精度姿态控制技术是小卫星技术中的一个关键技术。控制精度高和重量轻是适用于小卫星的两个基本特点。本文介绍了一种新的轻型高精度姿态控制系统。它采用衍射光学和折衍混合光学技术设计的星敏感器光学系统可以减少光学元件数目,具有重量轻、像质好,传光效率高的优点:运用先进的微电子集成技术,采用大规模可编程逻辑器件,设计研制高集成度的星像信号处理装置;利用复合轴控制技术,将姿态控制的精密部分作用在有效载荷的视轴上,这样可以降低对卫星的姿态控制要求,从而简化姿控系统,减轻重量。
Lightweight and high precision attitude control technology is a key technology in small satellite technology. Control of high precision and light weight are two basic characteristics of small satellites. This article describes a new lightweight high-precision attitude control system. Its star-sensor optical system designed by using diffractive optics and diffraction-mixed optical technology can reduce the number of optical components and has the advantages of light weight, good image quality and high light transmission efficiency. The use of advanced microelectronic integration technology and large-scale Programming logic devices, the design and development of highly integrated star image signal processing device; the use of composite axis control technology, the precision of the attitude control part of the payload on the visual axis, which can reduce the attitude control of satellite requirements, which simplify the attitude Control system, reduce weight.
