目前,法国正在执行一项军用卫星计划,研制三颗照相侦察卫星和一颗军用通信卫星,研制费在10年内约25亿美元。法国将在1992年7月用“阿里安—4”火箭发射第一颗“太阳同步照相侦察卫星”。卫星重2吨,采用三轴稳定,寿命可能三年以上。星上装有两架改进了望远镜头的高分辨率照相机,可拍可见光和近红外照片。尽管 At present, France is implementing a military satellite program to develop three photographic reconnaissance satellites and one military communications satellite, with development costs of about 2.5 billion U.S. dollars in 10 years. In July 1992, France will launch the first “sun-synchronized photographic reconnaissance satellite” with the “Arion-4” rocket. Satellite weighing 2 tons, using three-axis stability, life expectancy may be more than three years. The stars are equipped with two high-resolution cameras with improved telescope heads for both visible and near-infrared images. in spite of
