摘要
星敏感器作为一种高精度的空间姿态光学敏感器,在航天领域得到了广泛而深入的应用。随着我国航天事业的迅猛发展,提出了甚高姿态测量精度卫星的研制,其定位装置是通过星敏感器实现的。由此对于星敏感器自身标定的要求也越来越高。本文介绍了星敏感器的发展现状及其标定方法,标定方法包括地面标定和在轨标定。地面标定主要通过星模拟器等对星敏感器做标定和功能检测,而在轨标定则通过算法仿真及等实施。详细介绍了当今具有代表性的高精度星敏感器地面标定的方法和设备,提出各种方法并比较其优劣。最后针对标定技术存在的主要问题,分析了高精度星模拟器的发展方向,给出可能解决的方法和途径。
Star sensor as a high-precision optical sensor space,has been widely and in-depth application in space.With the rapid development of Chinese aerospace industry,a very high precision satellite attitude measurement is requined.The positioning device is achieved by the star sensor.Thus the star sensor calibration require increasingly.This article describes the development status of star sensor and calibration method,including the ground calibration and on-orbit calibration.Mainly through the star simulator ground calibration of satellite sensors such as calibration and function tests done,and on-orbit calibration algorithm for simulation and so on through the implementation.Details of today＇s typical high-precision star sensor ground calibration methods and equipment proposed and to compare their advantages and disadvantages of various methods.Finally,the main problems calibration,analysis of the development direction of high-precision star simulator have given the ways and means of possible solutions.
