Abstract

In recent years, the capacity of satellite has been improved by multi-beam technology. For the next-generation high throughput satellite (HTS), further improvements of capacity, flexibilization and digitization are required. In addition, cooperation with terrestrial 5G/Beyond 5G are also required to expand terrestrial network area or to utilize satellites as backup links in case of disaster or to realize completely new applications. We started research and development (R&D) on next-generation HTS which is scheduled for five years from fiscal year 2020 to fiscal year 2024. The development results will be verified by the on-orbit demonstration experiment using Engineering Test Satellite 9. In this paper, we introduce the outline of our R&D. In addition, we focus on one of the study items “satellite-terrestrial cooperation system” and present the concept of a satellite-terrestrial cooperation network simulator which will be used to extract potential issues or to verify some algorithms associated with the satellite-terrestrial cooperation system.

星地合作系统研究——多用例ka波段卫星通信控制研发的一部分

近年来，利用多波束技术提高了卫星的容量。对于下一代高通量卫星(HTS)，需要进一步提高容量、灵活性和数字化。此外，还需要与地面5G/超5G合作，以扩大地面网络面积或在灾难情况下利用卫星作为备份链路或实现全新的应用。从2020会计年度开始到2024会计年度为止的5年时间内，已经开始了下一代高温超导的研究开发(R&D)。开发结果将通过工程测试卫星9的在轨演示实验进行验证。本文介绍了本公司的研发概况。此外，我们重点研究了其中一个研究项目“星地合作系统”，并提出了星地合作网络模拟器的概念，该模拟器将用于提取潜在问题或验证与星地合作系统相关的一些算法。
