The Solar Guide Telescope (SGT), an important solar attitude sensor of theSST (Space Solar Telescope, a space solar observing instrument being developed in China), canaccurately produce pointing error signals of the SST for attitude control at high speed. We analyzein detail the error algorithm of the heliocentric coordinates and the edge judging of solar images.The measuring accuracy of +- 0.5 arcsec of the SGT is verified by experiments on the tracking of theSun and by testing a sun simulator. Some factors causing the pointing errors are examined. 展开更多
