Preliminary orbits with over-determined systems of Keplerian conservation laws
Clara Grassi, Giovanni Federico Gronchi
We consider different choices of Keplerian conservation laws for the computation of preliminary orbits with two very short arcs (VSAs) of astrometric observations. In total we have…

Revisiting the computation of the critical points of the Keplerian distance
Giovanni F. Gronchi, Giulio Baù, Clara Grassi
We consider the Keplerian distance in the case of two elliptic orbits, i.e. the distance between one point on the first ellipse and one point on the second one, assuming they h…
