国外遥感卫星发展简介(1)

从美国发射其第一颗遥感卫星一陆地卫星－1算起的30余年里,世界范围内商业遥感卫星技术已经有了巨大的进步,越来越多的国家和国际团体拥有自己的遥感卫星。除了更多各类的遥感器得以使用外,卫星的图像分辨率和覆盖能力也有了很大的改进。未来的发展更加令人振奋。国外遥感卫星（包括已经发射和计划要发射的卫星）简介是根据从国内外出版物中获得的信息整编而成,旨在给遥感应用提供一个现在和未来图像信息源的总的概念。

Brief Introduction on the Development of the Remote Sensing Satellite Abroad(1)

It is over 30 years since the 1st remote sensing satellite (land satellite) has been emitted in the U.S. A.. Since then, the commercial remote sensing satellite technology in the range of the world has been made great progress. More and more countries and international communities have possessed their own remote sensing satellites. Besides more different kinds of remote sensors being used, the revolution of image and the capacity of coverage of the satellite have also been much improved. The future development of them are quite exciting. The information of them(either emitted or be planned to be emitted) is brifed basing on the publications both at home and abroad, the purpose of the introduction is to provide a general concept about present and future image information sources for the application of remote sensing.
