Optimal flyby of space debris objects on a geostationary orbit

This work presents the results of numerical forecast for the movement of 92 space debris objects in a geostationary orbit. According to the calculation results, there were compiled the time variation graphs of: inclination, longitude of the ascending node, semi-major axis and eccentricity. Based on the obtained data we elaborated two flyby strategies of space debris objects and made an estimation of fuel costs as part of implementation of active debris removal schemes. The graphs of the change in inclination and the longitude of the ascending node represent the greatest interest, since the rotation of orbit plane by several degrees requires significant expenditures of the total characteristic velocity. The obtained results may be used for further elaboration of active debris removal schemes. © 2020, Univelt Inc. All rights reserved.
