据报道,在可持续陆地成像体系结构研究会议上,NASA宣布将和美国地质调查局(USGS)启动一个创新型且经济的天基系统。今年四月美国政府要求NASA对长期可持续的陆地成像系统进行研究,该系统规划时间至少20年,用于提供高质量的全球陆地成像观测。陆地卫星是美国开发的民用陆地资源卫星,也是对地观测系统(EOS)中的中分辨率遥感系统,从 It is reported that at the Sustainable Land Imaging Architecture Conference, NASA announced that it will launch an innovative and economical space-based system with the U.S. Geological Survey (USGS). In April this year, the U.S. government requested that NASA conduct a study on a long-term sustainable terrestrial imaging system that has been planned for at least 20 years to provide high-quality global terrestrial imaging observations. Terrestrial satellites are civilian land resources satellites developed by the United States and medium-resolution remote sensing systems in the Earth Observation System (EOS). From
