A novel conjunction filter based on the minimum distance between perturbed trajectories
Ana S. Rivero, Giulio Baù, Rafael Vazquez +1
The increasing congestion in the near-Earth space environment has amplified the need for robust and efficient conjunction analysis techniques including the computation of the minim…
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…
A dynamical definition of the sphere of influence of the Earth
Irene Cavallari, Clara Grassi, Giovanni F. Gronchi +2
The concept of sphere of influence of a planet is useful in both the context of impact monitoring of asteroids with the Earth and of the design of interplanetary trajectories for s…
Near-Linear Orbit Uncertainty Propagation in the Perturbed Two-Body Problem
Javier Hernando-Ayuso, Claudio Bombardelli, Giulio Baù +1
The paper addresses the problem of minimizing the impact of non-linearities when dealing with uncertainty propagation in the perturbed two-body problem. The recently introduced gen…
A generalization of the equinoctial orbital elements
Giulio Baù, Javier Hernando-Ayuso, Claudio Bombardelli
We introduce six quantities that generalize the equinoctial orbital elements when some or all the perturbing forces that act on the propagated body are derived from a disturbing po…
Generalization of a method by Mossotti for initial orbit determination
Giovanni F. Gronchi, Giulio Baù, Óscar Rodríguez +2
Here we revisit an initial orbit determination method introduced by O. F. Mossotti employing four geocentric sky-plane observations and a linear equation to compute the angular mom…
Non-averaged regularized formulations as an alternative to semi-analytical orbit propagation methods
Davide Amato, Claudio Bombardelli, Giulio Baù +2
This paper is concerned with the comparison of semi-analytical and non-averaged propagation methods for Earth satellite orbits. We analyse the total integration error for semi-anal…
Keplerian integrals, elimination theory and identification of very short arcs in a large database of optical observations
Giovanni Federico Gronchi, Giulio Bau, Andrea Milani
The modern optical telescopes produce a huge number of asteroid observations, that are grouped into very short arcs (VSAs), each containing a few observations of the same object in…
