所谓小卫星是指质量小于500kg的小型近地轨道卫星，它是80年代末随移动卫星通信技术的出现，以及对高分辨率图像的市场需求而迅速发展起来的。1背景90年代初，NASA下属的商业遥感项目办公室（CRSP）开始进行商业遥感小卫星的可行性研究。近年来，随着冷战的结束，前苏联的高分 The so-called small satellites are small-sized orbits of satellites less than 500 kg in mass mass. They were developed rapidly with the advent of mobile satellite communications in the late 1980s and the market demand for high-resolution images. 1 Background In the early 1990s, NASA’s Commercial Remote Sensing Project Office (CRSP) began a feasibility study of commercial remotely sensed small satellites. In recent years, with the end of the Cold War, the former Soviet Union’s high score
