High-resolution commercial satellite imagery from a growing number of private satellite companies allows nongovernmental analysts to better understand secret or opaque nuclear programs of countries in unstable or tense regions, called proliferant states. They include North Korea, Iran, India, Pakistan, and Israel. By using imagery to make these countries’ aims and capabilities more transparent, nongovernmental groups like the Institute for Science and International Security have affected the policies of governments and the course of public debate. Satellite imagery work has also strengthened the efforts of the International Atomic Energy Agency, thereby helping this key international agency build its case to mount inspections of suspect sites and activities. This work has improved assessments of the nuclear capabilities of proliferant states. Several case studies provide insight into the use of commercial satellite imagery as a key tool to educate policy makers and affect policy. Expected final online pub...

用于对抗核扩散的商业卫星图像分析

越来越多的私营卫星公司提供的高分辨率商业卫星图像使非政府分析人员能够更好地了解处于不稳定或紧张地区的国家（称为增殖国家）的秘密或不透明的核计划。它们包括朝鲜、伊朗、印度、巴基斯坦和以色列。通过使用图像使这些国家的目标和能力更加透明，科学与国际安全研究所等非政府组织已经影响了政府的政策和公共辩论的进程。卫星图像工作还加强了国际原子能机构的努力，从而帮助这个重要的国际机构建立了对可疑地点和活动进行检查的案例。这项工作改进了对增殖国家核能力的评估。几个案例研究提供了关于使用商业卫星图像作为教育政策制定者和影响政策的关键工具的见解。预计最终在线发布...
