... as used to evaluate the heliostat orientation. We therefore conclude that the relative RTK uncertainty is negligible for this method. In contrast, a potential systematic global positioning offset (with respect to the solar field) has a direct effect on the calibration results. However, the uncertainty...

... to increase the solar field efficiency, the main objective is to assure high-quality standards for the whole solar field. Quality control, assembly documentation, and performance measurements are required by the investors. Based on previous R&D work in collector development and prototype qualification...
