ABSTRACT:
A method of automatically aligning heliostats by comparing the actual sunbeam centroid position on a target to a command reference position to determine the error in the sunbeam centroid location.
The sunbeam centroid position error is then analyzed to correlate the error to errors in the heliostats' track alignment system. New coefficients are established for the heliostats' track alignment system to automatically correct for errors in the system, this eliminates the need for resurveying and field work normally associated with aligning heliostats.
