日本宇宙开发事业团研制的技术试验卫星Ⅵ(ETS—Ⅵ)是一颗设计寿命为10年、有效载荷比高达17.6％、姿态控制精度(滚动/俯仰:±0.05°;偏航:±0.15°)和轨道控制精度(东西、南北均为±0.1°)都非常高的三轴控制卫星,其主要特点是以氙电子轰击型离子发动机进行南北轨道控制,这也是世界上第一颗正式以电推力器作南北轨道控制的卫星,它将于1992年发射。宇宙开发事业团和三菱电机公司自1983年开始用了3年时间对这种直径为12cm、推力为25mN的以氙为推进剂的电子轰击式离子发动机进
The technology test satellite Ⅵ (ETS-Ⅵ) developed by Japan’s NASDA is a design life of 10 years with a payload ratio of up to 17.6%, attitude control accuracy (roll / pitch ± 0.05 °; yaw: ± 0.15 ° ) And orbital control accuracy (east-west, north-south are ± 0.1 °) are very high three-axis control satellite, which is characterized by xenon electron bombardment ion engine orbital orbit control, which is the world’s first official electricity Thrusters for North orbital orbit control satellite, which will be launched in 1992. Cosmic Development Corps and Mitsubishi Electric spent three years starting in 1983 on this xenon propellant electron impact ion engine with a diameter of 12 cm and a thrust of 25 mN
