Here we show how to determine the orbital parameters of a system composed ofa star and N companions (that can be planets, brown-dwarfs or other stars),using a simple Fourier analysis of the radial velocity data of the star. Thismethod supposes that all objects in the system follow keplerian orbits aroundthe star and gives better results for a large number of observational points.The orbital parameters may present some errors, but they are an excellentstarting point for the traditional minimization methods such as theLevenberg-Marquardt algorithms.
