On the Sun-shadow dynamics
Irene Cavallari, Giovanni Federico Gronchi, Giulio Bau'
We investigate the planar motion of a mass particle in a force field defined by patching Kepler's and Stark's dynamics. This model is called Sun-shadow dynamics, referring to the m…

Uniform formulation for orbit computation: the intermediate elements
Giulio Baù, Javier Roa
We present a new method for computing orbits in the perturbed two-body problem: the position and velocity vectors of the propagated object in Cartesian coordinates are replaced by…

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…
