A series of numerical filters was applied to filter out spurious data. The positions of Uranus were then indirectly determined by computing the mean differences between the observed and ephemeris positions of these satellites. We used the software called Platform for Reduction of Astronomical Images Automatically (PRAIA) to perform a digital coronography to minimise the influence of the scattered light of Uranus on the astrometric measurements and to determine accurate positions of the main satellites. All runs were made at the Pico dos Dias Observatory, Brazil. The observational period spans from 1992 to 2011. Positions of Uranus, as derived from those of these satellites, are also determined. We determine accurate positions of the main satellites of Uranus: Miranda, Ariel, Umbriel, Titania, and Oberon. We contribute to developing dynamical models of the motions of Uranus’ main satellites.Īims. 070-200 Rio de Janeiro RJ, BrazilĬontext. Manual Caldeira de Alvarenga 1203, CEP 23.
