“实践9号”卫星电推进首次在轨试验验证

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

"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。

SJ-9A/B satellite is the first one of new science exploration and technology demonstration spacecraft system.It waslaunched successfully on Oct,14th,2012.SJ-9A satellite fulfilled its task and mission after over three years of test evaluation andtechnology demonstration.The Hall electric propulsion and ion electric propulsion are validated in orbit at first on SJ-9satellite,while their performances are calibrated.The Hall and ion electric thrusters are tested more than200times respectively,and theirperformances satisfy all requirements.
