任务简介
SATMEX 5 是休斯 HS-601HP 或“高功率”版本的三轴稳定航天器。其有效载荷功率超过 7000 瓦，至少是 Morelos II 的 10 倍。通过双结砷化镓太阳能电池、辐射冷却行波管放大器、先进电池技术以及氙离子推进系统等创新，HS-601HP 可承载比 HS 601 型号强大两倍的有效载荷，预期任务寿命为 15 年。
原文
SATMEX 5 is a Hughes HS-601HP or "high power" version of the body-stabilized spacecraft. It features more than 7,000 Watts of payload power, at least 10 times the capacity of Morelos II. Through such innovations as dual-junction gallium arsenide solar cells, radiation-cooled traveling-wave tube amplifiers (TWTAs), advanced battery technology, and a xenon ion propulsion system, XIPS, the HS-601HP can carry payloads twice as powerful as those on the HS 601 models, with an expected 15-year mission lifetime.
