现代小卫星领域的发展现状分析

Analysis of current developments in the field of modern small satellites

现代小卫星不仅可用于民用市场,还可以满足各种机动任务的需求,特别是对军事航天的发展具有极其重要的作用。结合国际上的最新发展情况,对现代小卫星作了概述,总结了现代小卫星的分类和发展过程、发展模式、优缺点和不同阶段的技术特征;从卫星设计总体角度指出了现代小卫星未来发展所面临的若干挑战以及大、小卫星并存和优势互补的必要性;归纳了现代小卫星星群的应用情况,分析了编队、星族和星座的技术和应用特征,指出了小卫星未来发展方向。

Nowadays,modern small satellites are playing a very important role in both the civilian market and meeting the needs of various maneuverable tasks, especially for the development of military aerospace. In this paper, given the latest international developments, we make make a general overview about the modern small satellites. Also, we summarize the classification and development of the modern small satellites, inclu- ding models, advantages and disadvantages, and technical features of different stages. In the overall perspec- tive of the satellite design, we also point out some challenges that the future development of the modem small satellites will face, and analyze the necessity of the large and small satellites to coexist and complement with each other. Besides, we summarize the application of the modern small satellites constellation, analyze the technology and application features of formation, stellar and constellations, and finally point out the direc- tion of the future development of modern small satellites.
