地球静止轨道(GEO)是人类仅有的一条独特卫星轨道,是极其珍贵的轨道资源。首先分析了GEO环境现状和未来趋势,然后从“GEO轨道保护”和“GEO卫星在轨维护”两方面论述了GEO在轨服务技术的内涵、服务机会和效益,介绍了世界各国GEO在轨服务技术的主要研究进展,归纳了其中的关键技术。最后,对未来的发展趋势进行了展望。
The Geostationary orbit (GEO), a unique satellite orbit of the human beings, is very precious orbit resource. Firstly, the current status and future trends of the GEO environment are analyzed. Then, we address the connotation, service chance, and benefits of the orbital servicing in GEO, from the two aspects of 'Protection of the GEO orbit' and 'On-orbit maintenance of the GEO satellites' . The main achievements of the countries in the world are introduced, and the key technologies of GEO orbital servicing are summarized. Finally, the research prospects are presented.
