“海盗-A”是瑞典第一颗卫星,它用来测量磁层界面场和研究极光。这种低费用卫星的特点也能应用于其它小型卫星上。“海盗-A”于1986年2月22日用“阿里安-3”火箭发射成功。瑞典本土的一部分处于极光带,因而电离层和磁层研究在瑞典科研中一直占较重要的位置。他们曾进行过探空火箭、高空气球、卫星以及陆上实验测量等工作。七十年代后期他们又提出要用瑞典卫星作进一步的磁层界面和极光研究,以获得在实验室难以 Pirate-A is the first Swedish satellite to measure the magnetosphere interface field and study auroras. The features of this low-cost satellite can also be applied to other small satellites. “Pirate-A” was successfully launched on February 22, 1986 with the “Arion-3” rocket. As a part of the Swedish land is in the auroral zone, ionospheric and magnetospheric studies have always been of central importance to Swedish research. They have conducted sounding rockets, high-altitude balloons, satellites and land-based experimental measurements. In the late seventies they also proposed using Swedish satellites for further study of the magnetosphere interface and auroral to obtain the difficulty in the laboratory
