本文把空间电子学归纳为对卫星和空间飞行器实现跟踪控制,利用卫星观测地球、深空探测、卫星通信广播以及利用卫星对地球上运动物体的定位等方面的无线电电子技术。文中举出了一些近年来较为突出的空间电子系统的成就,分析了空间电子学的特点,还简略地介绍了我国的发展概况。最后简要地展望了未来的发展。 This article summarizes space electronics as a radio-electronic technology that tracks and controls satellites and space vehicles, observes the Earth using satellites, deep space exploration, satellite communications broadcasts, and the positioning of moving objects on Earth using satellites. In this paper, some achievements of the space electronic system that have been outstanding in recent years are given, the characteristics of space electronics are analyzed, and the general situation of China’s development is briefly introduced. Finally, a brief overview of the future development.
