Ship attitude measurement accuracy based on star sensors is relative to the calibration accuracy of the installation angle between star sensor and ship desk. This paper introduces the coordinate system of the shipboard star sensor and the definition of installation angle. Then
it establishes a model to correct the atmospheric refraction of the sensor and proposes a calibration method for installation angle of the high accuracy shipboard star sensor. When the space TT & C ship docks in shipyard
shipboard theodolite determines the course of the ship by shooting the azimuth mark
and star sensor obtains the ascension and declination of the stars in the field of view by star recognition to construct the star reference vectors with respect to inertial space. After correction of precession
nutation
pole shift and ship position
the star reference vectors with respect to Inertial Navigation System(INS) horizontal coordinate system are obtained. According to the atmospheric refraction correction model
each star in the field of view corrects its pitch angle and reconstructs its star reference vector with respect to INS horizontal coordinate system. Finally
star sensor installation matrix is calculated based on the principle of attitude determination algorithm
and then three installation angles are solved. Experiment results show that the calibration accuracy of azimuth and pitch using proposed method reach less than 10". The proposed method is based on the higher pointing accuracy of the star sensor and improves automatic programming and measuring accuracy of ship attitudes.
