Abstract: 34 astronomical positions of URANUS and Satellites ARIEL, UMBRIEL, TITANIA, OBERON are given as obtained from photographic observations made at ESO La Silla, in May 1980, with the Astrograph GPO (Grand Prisme Objectif: focale=4 m, diameter=40 cm). The bijections between the tangentials planes X, Y rectilinear celestial or standard coordinates and the plates x, y measures are determinated by means of 5 reference stars and with two methods: dependences and least squares.
