新一代卫星回传系统设计需求分析

Analysis of Needs of New-generation Satellite Return System’s Design

为配合我国新一代直播卫星技术ABS-S(Advanced Broadcasting System by Satellite)的发展应用,新一代卫星回传系统的研究设计成为业内的关注点之一。本文首先明确了我国发展新一代卫星回传系统的必要性和可行性,并从多个方面详细分析了系统设计的商业需求,为设计具有自主知识产权的符合ABS-S技术发展的卫星回传系统做了前期产业基础研究铺垫。

ABS-S, China’s Direct Broadcasting Satellite Technology Standard, has been adopted in the Project of'Extending Broadcasting Coverage to Every Village', so it has great significance, under trends of Three Networks Convergence, to research the satellite return system (SRS) integrating with ABS-S. The paper discusses feasibility of China’s SRS transmission technology, and analyses business needs of SRS design. The earlier stage research of SRS design, which has proprietary intellectual property rights and accords with the development of ABS-S, has been done.
