We present a new theory of the four Galilean satellites Io, Europa, Ganymede and Callisto. This aims to deliver highly accurate ephemerides able represent satellites' motion over several centuries. It is based on numerical integration elaborated equations motion. first paper describes tests many usually neglected perturbations. are then retain some them in dynamical model for system. A method developed adjust observations given. used general formalism so it can be extended systems other than one. As an example this method, we compare our current E5 Galileans.
