Pointing error correcting system and method thereof

摘要

The present invention discloses a pointing error correcting system and method thereof applied for a concentrated photovoltaic or solar heat energy system comprising a processing module, a driving module, a tracker and a measuring module. The method comprises steps of calculating a position of a celestial body; controlling the driving module to drive the tracker pointing toward the celestial body; calculating an error value between the pointing of the tracker and the celestial body measured by the measuring module through a coordinate transforming method; and correcting the driving module to drive the tracker pointing the celestial body.
