阿里安空间公司于1991年7月用“阿里安40”火箭发射欧空局(ESA)的“欧洲地球资源卫星(ERS-1)”,并附带发射美、法、德、英的4颗小型实验卫星。 ERS-1发射至倾角98.5°、高度785km的太阳同步极轨道上。由于阿里安空间公司发射至极轨的卫星频率每年还不足1次,因此,它至今还没有能独立经营的跟踪管理站,必须依靠美国的支援。将用美国家海洋大气局(NOAA)设置在阿拉斯加州费尔班克斯的遥测接收专用站,编入最初确认卫星入轨的程序中。同时发射的小型卫星分离机构安装部件由法国马特拉公司研制。称为“阿里安辅助
In July 1991, Alian Space Company launched the ESA’s “Earth Resources Satellite (ERS-1)” with the “Arion 40” rocket and launched four small-scale aircraft of the United States, France, Germany and Britain Experimental satellite. The ERS-1 is launched onto a solar synchronous polar orbit at an inclination of 98.5 ° and a height of 785 km. Since Arianespace launched less than one satellite per year on polar orbit, it still has no independent tracking management station and must rely on U.S. support. A dedicated telemetry receiving station set up by the United States National Oceanic and Atmospheric Administration (NOAA) in Fairbanks, Alaska, will be programmed into the initial confirmation of satellite orbital procedures. Simultaneous launch of small satellite separation mechanism installation components developed by the French company Matera. Called "Arian Assist
