Star Sensor Calibration Research and Development

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.
