Updating the PSA sun position algorithm
Manuel Blanco, Kypros Milidonis, Aristides M. Bonanos
Abstract
The algorithm for computing the solar vector of (Blanco et al., 2001) is revisited to improve its accuracy in the period 2020–2050, a period for which the algorithm was not initially designed. The resulting improved algorithm achieves a 25% decrease in the average error of the angular deviation with respect to the true solar vector (from a mean error of 11.81–8.78 arcsec), while simultaneously decreasing the range of variation of the error.
