从运营角度探讨GEO卫星演进关键技术
Exploring Key Technologies for GEO Satellite Evolution from an Operational Perspective
摘要
Abstract
Against the background of the gradual transformation of satellite communications into networked operation,the operation idea of improving utilization efficiency of Geostationary Orbit(GEO)satellite resources and reducing communication cost is put forward in response to the challenges posed by low-orbit constellations to the operation of GEO satellite in recent years.On this basis,combining the three important application scenarios of time and space changing service demand,high-value mobile carrier,and space-terrestrial co-operative ubiquitous interconnection faced by the future development of satellite communication,key technologies of GEO satellite to im-prove the cost-effectiveness of services are analyzed according to characteristics of each scenario,including the satellite flexible payload technology and the satellite-cellular network convergence technology.Then architecture and functional points of these technologies are pointed out,as well as the important impact on the utilization of satellite resources after implementation of the technologies.关键词
