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…
