论文摘要
卫星通信最近进入了一个以技术进步动机激励的新兴趣，并通过私人投资和企业进行了培养。本调查旨在捕捉SATCOM的最新技术，同时强调最有希望的开放研究主题。首先，主要的创新驱动程序是动机的，例如新的星座类型，车载处理能力，非事务网络和基于空间的数据收集/处理。其次，描述了最有希望的应用，即5G整合，空间通信，地球观察，航空和海上跟踪和通信。随后，在五个轴上提供了深入的文献综述：i）系统方面，ii）空气界面，iii）中等访问，iv）网络，v）测试床和原型化。最后，描述了许多未来的挑战和各自的开放研究主题。
Satellite communications have recently entered a period of renewed interest motivated by technological advances and nurtured through private investment and ventures. The present survey aims at capturing the state of the art in SatComs, while highlighting the most promising open research topics. Firstly, the main innovation drivers are motivated, such as new constellation types, on-board processing capabilities, nonterrestrial networks and space-based data collection/processing. Secondly, the most promising applications are described i.e. 5G integration, space communications, Earth observation, aeronautical and maritime tracking and communication. Subsequently, an in-depth literature review is provided across five axes: i) system aspects, ii) air interface, iii) medium access, iv) networking, v) testbeds & prototyping. Finally, a number of future challenges and the respective open research topics are described.
