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…
Numerical behavior of the Keplerian Integral methods for initial orbit determination
Óscar Rodríguez, Giovanni F. Gronchi, Giulio Baù +1
We investigate the behaviour of two recent methods for the computation of preliminary orbits. These methods are based on the conservation laws of Kepler's problem, and enable the l…
Linking tracklets over the years in large datasets
Óscar Rodríguez, Giovanni F. Gronchi, Giulio Baù +1
We present a new procedure to identify observations of known objects in large data sets of unlinked detections. It begins with a Keplerian integrals method that allows us to link t…
Orbit determination from one position vector and a very short arc of optical observations
Erica Scantamburlo, Giovanni F. Gronchi, Giulio Baù
In this paper we address the problem of computing a preliminary orbit of a celestial body from one topocentric position vector and a very short arc (VSA) of optical observations. U…
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…
Maps of secular resonances in the NEO region
M. Fenucci, G. F. Gronchi, B. Novaković
Context. From numerical simulations, it is known that some secular resonances may affect the motion of near-Earth objects (NEOs). However, the specific location of the secular reso…
