Theoretical derivation of heliostat tracking errors distribution

The tracking error probability distribution is derived on a pure theoretical basis. Methods of integral geometry and geometrical probabilities are used to this purpose. The distribution performs reasonably well when compared with measurements from a small database. The performance of the theoretical...

Description
Summary:The tracking error probability distribution is derived on a pure theoretical basis. Methods of integral geometry and geometrical probabilities are used to this purpose. The distribution performs reasonably well when compared with measurements from a small database. The performance of the theoretical distribution is compared with that of other (empirical) probability distributions. The practical relevance of using the present approach is also explained.
