Resonant Orbital Dynamics in LEO Region: Space Debris in Focus

Abstract

The increasing number of objects orbiting the earth justifies the great attention and interest in the observation, spacecraft protection, and collision avoidance. These studies involve different disturbances and resonances in the orbital motions of these objects distributed by the distinct altitudes. In this work, objects in resonant orbital motions are studied in low earth orbits. Using the twoline elements (TLE) of the NORAD, resonant angles and resonant periods associated with real motions are described, providing more accurate information to develop an analytical model that describes a certain resonance. The time behaviors of the semimajor axis, eccentricity, and inclination of some space debris are studied. Possible irregular motions are observed by the frequency analysis and by the presence of different resonant angles describing the orbital dynamics of these objects.

Synchronous satellites in circular or elliptical orbits have been extensively studied in literature, due to the research of resonant orbits characterizing the dynamics of these satellites (see [SAMPAIO et al, 2012a[SAMPAIO et al, , 2012b[SAMPAIO et al, , 2014 and references here in)…”

Space Debris: Reentry and Collision Risk

“…A previous study, described in [3], shows a large research in resonant regions with several objects, including space debris. Results show that most of objects are in the region 13 < n < 16, where n is the mean motion.…”

“…The propagation method shown in the present work considers effects of the geopotential and atmospheric drag, see Eqs. 7 to 19, while previous works, see [3] and [4], they consider only corrections in the TLE data and effects of the geopotential in the orbital dynamics of space debris shown by Eqs. 1 to 6.…”
