The First On-Orbit Technology Demonstration for the Electric Propulsion of SJ-9 Satellite

Abstract

SJ-9A/B satellite is the first one of new science exploration and technology demonstration spacecraft system. It was launched successfully on Oct，14th，2012. SJ-9A satellite fulfilled its task and mission after over three years of test evaluation and technology demonstration. The Hall electric propulsion and ion electric propulsion are validated in orbit at first on SJ-9 satellite，while their performances are calibrated. The Hall and ion electric thrusters are tested more than 200 times respectively，and their performances satisfy all requirements.
