Abstract: Contents observables (e.g. the range, with radar telescopes), but also to the huge amount of data that can be collected. For these reasons scientists have been induced to think about new algorithms to compute orbits. In this chapter we present a review of some orbit determination methods, with particular care about the computation of preliminary orbits. Here we include both classical methods, due to Gauss and Laplace, and very recent ones, which are suitable for the sets of optical observations made with moder…
