我国今年计划进行6次卫星发射,其中之一就是将于10月份用长征四号运载火箭从太原发射中心起飞发射1颗地球资源卫星。根据1996年11月8日中国和巴西签署的“关于和平利用外层空间科技合作联合声明”的规定,这颗卫星就是中巴两国合作研制的第一代传输型地球资源卫星资源一号。地球资源卫星是勘测和研究地球自然资源的人造卫星。它利用本身携带的多光谱遥感设备获取地物目标辐射或反射的电磁波信息,并将这些信息发送给地面接收站。地面接收站根据事先掌握的各类物质的波谱特性,对收到的信息如卫星照片等使用计算机进行处理,从而得到各类资源的特征、分布和状况等资料。由于这类卫星能迅速、全面和经济地提供地球资源的情况,对于资源开发和发展经济有着重要作用,因而越来越受到国际社会的重视。利用地球资源卫
China plans to conduct 6 satellite launches this year. One of them is that it will launch a Earth resources satellite from the Taiyuan Launch Center in October using the Long March IV launch vehicle. According to the “Joint Statement on Scientific and Technological Cooperation in the Peaceful Uses of Outer Space,” signed by China and Brazil on November 8, 1996, the satellite is the first satellite resource of transmitted earth resources jointly developed by China and Brazil. number. Earth Resources Satellites are satellites that survey and study Earth’s natural resources. It uses its own multispectral remote sensing equipment to obtain the target radiation or reflected electromagnetic wave information, and send this information to the ground receiving station. Based on the spectral characteristics of various substances that have been grasped in advance, the ground receiving station processes the received information, such as satellite photos, using a computer to obtain the characteristics, distribution and status of various resources. Because such satellites can provide Earth resources promptly, comprehensively and economically, and play an important role in resource development and economic development, they have drawn more and more attention from the international community. Use of Earth resources guard
