发达国家的几种卫星应用考虑

Satellite Application Considered by Some Developed Countries

介绍了加拿大、美国、德国、法国不同的卫星应用考虑。加拿大拟用2颗卫星在2007年前后获得近乎全球高精度的地球高低数据,美国着重于开发全球性的侦察和作战用的卫星群,德国和法国则试图用一发数收小卫星来解决SAR/MTI。

This paper describes spacebome satellites of four developed countries that is Canada, USA, Germany and France. Two satellites developed by Canada are used for highly accurate earth altitude measurement. Satellites groups are being developed by USA mainly for surveillance before and during the war. The satellites with one transmitter and four and three small receivers are being developed by Germany and France to use for SAR/MTI.
