On the Application of Electric Propulsion in Geostationary Space Debris Mitigation

It is a measure using electric propulsion to the mitigate the geostationary space debris. The electric propulsion feasibility and effect in space debris mitigation were studied. Through studying the characteristics, development, and application of ion propulsion, it states that a geostatonary satellite can be effectively moved to "debris orbit" by electric propulsion at the end of life. Based on spacecraft orbit transfer theory, the scenario which acting constant thrust of electric propulsion along velocity vector, and using multi-times double impulse orbit transfer in space debris mitigation was studied. By means of simulation, the calculating methods and scale effects of thrust scale, each continued time, total transfer time, characteristic velocity and propellant quantity were gained, and the action and effect of electric propulsion in space debris mitigation were testified. Realizing impulse manner scheme of electric propulsion in orbital transfer was investigated.
