Abstract
A drive assembly for a heliostat is described, wherein the drive assembly may be configured to dynamically adjust the position of an attached reflector in concentrated solar power applications. The drive assembly may be further configured to provide for biasing of the reflector to reduce backlash due to external loads. The biasing force may be provided by at least one of a spring, counterweight, or offset of the center of gravity of the reflector or other attachment, or some combination thereof.
