Satellite Communications in the New Space Era: A Survey and Future Challenges - IEEE

 
   
Satellite communications (SatComs) 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, non-terrestrial 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.

 

Since their inception, Satellite Communications (SatComs) have found a plethora of applications, including media broadcasting, backhauling, news gathering etc. Nowadays, following the evolution of Internet-based applications, SatComs are going through a transformation phase refocusing the system design on data services, namely broadband SatComs. The main motivation is a) the rapid adoption of media streaming instead of linear media broadcasting and b) the urgent need to extend broadband coverage to underserved areas (e.g., developing countries, aero/maritime, rural). Furthermore, a major milestone of the 5th generation of communication systems (5G) is the integration and convergence of diverse wired and wireless technologies. In this context, SatComs pave the way for seamless integration targeting specific use cases which can take advantage of their unique capabilities. In parallel, private ventures have led the development of a multitude of manufacturing and launching options, previously only reserved for governments and a handful of large international corporations. This initiative named New Space has spawned a large number of innovative broadband and earth observation missions all of which require advances in SatCom systems.
