Long-Time Predictions of Satellite Orbits by Numerical Integration
In this paper we aim at establishing limits of predictability to find the extension of time for which meaningful analytical and/or numerical predictions can be made in orbital behaviour of artificial satellites. These limits depend, of course, on the accuracy required, on the specific dynamical models formulated, on the sets of variables chosen to describe them, on the numerical or analytical techniques used and, especially, on the specific trajectories to be established. In order to check the reliability of the predictions, first integrals, constraints among redundant variables and backwards integrations from the ending point to the initial conditions have been used.
