The First On-Orbit Technology Demonstration for the Electric Propulsion of SJ-9 Satellite
-
摘要:
“实践9号”A/B新技术试验卫星于2012年10月14日在太原卫星发射中心成功发射,经过3年多的在轨考核和试验验证,圆满完成了卫星使命,其中离子和霍尔电推进在轨首次试验验证,进行了性能标定,分别进行了200余次的点火试验,各项指标满足要求。为我国的电推进技术的在轨应用奠定了基础。
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.
