摘要
结合主流离子和霍尔电推进技术特点,介绍其用于地球同步轨道(GEO)卫星和低地球轨道(LEO)卫星的不同优势。从空间任务定位、产品特点、不同轨道高度空间环境差异等角度,分析电推进技术发展在轨道转移、高精度推力矢量控制等方面的总体需求及应用特点。提出电推进技术在通信卫星领域工程化应用在指标、布局、卫星匹配性等方面的系统设计思路,以及产品化、电磁兼容性设计、可靠性和长寿命验证等方面的发展建议,可为后续电推进产品研制提供参考。
Based on the characteristics of mainstream ion and Hall electric propulsion technologies,their different advantages for GEO(geosynchronous earth orbit)and LEO(low earth orbit)communications satellites is described.The overall requirements and application characteristics of electric propulsion technology development in terms of orbit transfer and high-precision thrust vector control are analyzed from the perspectives of space mission,product characteristics and space environment differences at different orbital altitudes.Then the system design ideas for the engineering application of electric propulsion technology in the field of communications satellites are proposed in terms of indicators,layout and satellite matching,and other aspects,as well as the development suggestions for productization,electromagnetic compatibility design,reliability and long life verification are given,which can provide references for the subsequent development of electric propulsion products.
