Nowadays star sensor technology used in aircraft attitude measurement has become more and more popular for its high precision
light weight
without attitude accumulation errors and other advantages. In order to enhance the accuracy of star sensor
it is critical to make efforts to promote the precision of star image locating. High precision star image locating method mentioned in this article includes two aspects. One is sub-pixel dividing algorithm used to acquire the coordinate of stars. The other one is imaging calibration method used to weaken the effect caused by imaging distortion. This method is finally realized in some type of star sensor system. Then an experiment is designed to verify the precision of the method. The result of the experiment shows that the precision of the method is 2" in the experimental environment. 2010 IEEE.
