A Survey on Nongeostationary Satellite Systems: The Communication Perspective

The next phase of satellite technology is being characterized by a new evolution in non-geostationary orbit (NGSO) satellites, which conveys exciting communication capabilities to provide non-terrestrial connectivity solutions and support wide range digital technologies from various industries. NGSO systems are known for number key features such as lower propagation delay, smaller size, signal losses comparison the conventional geostationary (GSO) can potentially enable latency-critical applications be provided through satellites. promises substantial boost speed energy efficiency, thus, tackling main inhibiting factors commercializing GSO satellites broader utilization. promised improvements have motivated this paper comprehensive survey state-of-the-art research focusing on prospects, including physical layer radio access along with networking aspects overall system architectures. Beyond this, there still many deployment challenges addressed ensure seamless integration not only but also terrestrial networks. These unprecedented discussed paper, coexistence terms spectrum regulatory issues, constellation architecture designs, resource management problems, user equipment requirements. Finally, we outline set innovative directions opportunities future research.
