| Abstract: | Star sensor is a high precision attitude measurement instrument.Structure design and precision calibration method of high-accuracy star sensor is discussed in this paper.The measure errors of optical system can be decreased by using design of big visual angle and relative diameter lightly optical system.Design methods of specular baffle and focus plane assembly are introduced.The precision calibration method of star sensor is presented.The system errors can be diminished as far as possibly by this way.The sensor is calibrated and tested by leica theodolites.It is testified that the precision of star sensor is met,which the precision of single star is less than 3 second. |
