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.
