A Study on PMD Device for Microsatellites Using Electrodynamic Tether

A deorbit device is required for some microsatellites to meet space debris mitigation guidelines, although very challenging in terms of limited resources and reliability. The authors are conducting research on post-mission disposal (PMD) devices using an electrodynamic tether due its high efficiency simplicity. This PMD consists a deployment system, electron emitter, integrated control system. effectiveness were investigated by numerical simulation ground experiments. effects the performance various parameters evaluated considering such precise models as those used plasma density geomagnetic field. We confirmed system brake In this paper, results initial study presented.
