美国先进极高频（AEHF）项目将采用4颗运行于地球同步轨道（GEO）的AE—HF军事通信卫星。AEHF卫星的推进系统由远地点发动机、姿态控制发动机组和双模式霍尔电推进子系统组成。首发星AEHF-1是世界上首个采用霍尔电推进系统执行发射后轨道提升任夯的GEO卫星。AEHF-1卫星星箭分离后，远地点发动机未能正常工作，因此只能采用其余两套推进子系统执行轨道提升任务，并提前启用霍尔电推进子系统，以确保卫星寿命。对AEHF项目、AEHF卫星及其推进系统，以及星箭分离后AEHF-1卫星推进系统的应用情况进行论述，为我国GEO卫星采用双模式霍尔电推进系统执行轨道提升和在轨位置保持任务提供参考。

Four GEO AEHF military communication satellites will be employed in USA AEHF program. The propulsion system of AEHF satellite consists of apogee engine, attitude control engine assembly and dual-mode Hall electric propulsion subsystem. The first AEHF satellite, AEHF-1, is the first GEO satellite with Hall electric propulsion system for orbit raising after liftoff. Because of the malfunction of the apogee engine on AEHF-1 after the propulsion rocket was separated from AE- HF-1, the other two propulsion subsystems were used for orbit raising, while Hall electric propulsion system started in advance to maintain the satellite life. AEHF program, AEHF satellite and its propul- sion system, and the propulsion system application of AEHF-1 satellite is introduced, so as to provide a reference for using dual-mode Hall electric propulsion system for orbit raising and in-orbit position keeping of Chinese GEO satellites.
