Abstract
In order to improve the precision of ship-borne star sensor, the attitude error model is theoretical analyzed in this paper. Firstly, in view of the actual working environment on the ship, the observation model of ship-borne star sensor is constructed. Then the error model expressions based on angle observa-tion are deduced. Finally, the horizontal roll angle error and installation angle of ship-borne star sensor that can influence the ship attitude precision are analyzed by simulation. The results of theoretical analysis and simulation indicate that the horizontal roll angle measurement error, the calibration error of installation angle and the installation layout of the ship-borne star sensor on the ship are the main factors of the ship attitude measurement precision. For example, as the horizontal roll angle error is 100", the ship attitude error can reach 112". The installation layout of the ship-borne star sensor has some effects on precision, in which the ship attitude error oscillates with increasing installation azimuth, the pitch angle error increases with installation elevation. When the star sensor is arranged along the fore and aft line, the course error in-creases with the increasing installation elevation, and when orthogonal to the fore and aft line, the ship roll error increases with the increasing installation elevation.关键词
