一、前言定向太阳帆板是指卫星上可对太阳跟踪定向的太阳电池供电系统。采用这种定向太阳帆板可显著缩小帆板面积并能提高其比功率。它一般用于三轴稳定的地球卫星,例如,气象、资源、通信、广播、导航卫星等。由于此类卫星要求其Z轴始终指向地心,因而不能使太阳帆板同时对准太阳。这样,便采用了定向太阳帆板。定向太阳帆板是在伸展式(不定向)太阳帆板的基础上发展起来的。它出现在六十年代末期,至今在国外已获得广泛地应用。例如,美国的Nimbus—1气象卫星、FLTSATCOM
First, the foreword Directional solar panels refers to the satellite solar tracking system can be oriented solar battery. The use of this directional solar panel can significantly reduce the windsurfing area and increase its specific power. It is generally used for three-axis stable earth satellites, for example, weather, resources, communications, broadcasting, navigation satellites and the like. Since such satellites require that their z-axis always point to the center of the Earth, they can not align the solar panels to the sun at the same time. In this way, directional solar panels are used. Directional solar panels are based on extended (non-directional) solar panels. It appeared in the late 1960s and has been widely used abroad so far. For example, the United States Nimbus-1 weather satellite, FLTSATCOM
