“…Finally, to start the computations for autonomous tracking, we assume that S is maneuvered until the orbital elements of S and D coincide, except for the orbital eccentricity and the semimajor axis. The semimajor axis of S is required to be larger than the one of D. According to [13], for S to become autonomous the perigee of the orbit of S is assumed to be aligned with the perigee of the orbit of D and with the ECI center. The eccentricity of S is then adapted in such a way that S and D have the same velocity at perigee (If the orbit of D is circular, then the integration starts when S is at perigee and S and D are aligned with the ECI center.…”

In this paper, we introduce a computational procedure that enables autonomous LEO laser trackers endowed with INSs to increase the current accuracy when shooting at middle distant medium-size LEO debris targets. The code is designed for the trackers to throw the targets into the atmosphere by means of ablations. In case that the targets are eclipsed to the trackers by the Earth, the motions of the trackers and targets are modeled by equations that contain post-Newtonian terms accounting for the curvature of space. Otherwise, when the approaching targets become visible for the trackers, we additionally use more accurate equations, which allow to account for the local bending of the laser beams aimed at the targets. We observe that under certain circumstances the correct shooting configurations that allow to safely and efficiently shoot down the targets, differ from the current estimations by distances that may be larger than the size of many targets. In short, this procedure enables to estimate the optimal shooting instants for any middle distant medium-size LEO debris target.

“…For this reason, we assume that all orbital elements of S and D are zero, except for those in Table 1. In particular, the first two cases correspond to autonomous trackers S, so that, as was said in Section 2, their orbital eccentricities are adapted to the orbits of the respective D [13].…”
