“…The challenge inflected by the ever-growing NGSO systems and mega-constellations that are launched for various space applications is the necessity for a real-time uninterrupted connectivity, which is fairly infeasible in current satellite system infrastructure due to the magnitude and cost of the needed gateway network on ground. Thereby, there is a demand for the development of new space network infrastructures to supplement and extend the satellite communication systems [170], [171]. To this end, satellites can be deployed as a space information network (SIN) using ISLs and inter-orbit links (IOLs) as illustrated in Fig.…”

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

“…The inherent reason causing all the above mentioned problems is that traditional space systems are mainly built for specific users(demands), and lose compatibility among each other. Therefore, to overcome those limitations mentioned before, the concept of space information network (SIN) emerges as the times require [1].…”

Space information network (SIN) plays an extremely important role in civil and military applications. However, a specific definition of SIN still remains a challenging issue. Unlike space communication network (SCN), which merely focuses on information delivery, SIN has the ability to process the delivered information and providing corresponding services based on the information, which makes SIN seem to be able to understand information. This paper offers architecture and corresponding network model for timespace uninterrupted SIN. Initially, both physical and logical constitution of SIN architecture are presented with several corresponding constellation designs, which is the fundamental work for setting nodes in SIN. Based on this SIN architecture, a hierarchical autonomous system (AS)-based network model for SIN is proposed in order to manage SIN more efficiently by separating the whole network into several relatively stable ASs. Furthermore, we analyze topology control schemes and network capacity trend of AS-model based SIN. This paper gives the future research directions in the conclusion. INDEX TERMS Constellation design, hierarchical autonomous system, network capacity, space information network, topology control.

“…Recently, with the fast development of space exploration, the space information network (SIN) becomes an attractive and hot research field. [1][2][3][4][5][6] The concept of SIN was first proposed in 1998. To spread the terrestrial Internet to the space, the Defense Advanced Research Projects Agency (DARPA) supported the Jet Propulsion Laboratory (JPL) to investigate space Internet to realize end-to-end communications.…”

“…And some key technologies of SIN were discussed in Dai and Zhu. 5 Nishiyama et al 6 proposed a promising multilayered satellite network to provide global ubiquitous broadband communication and discussed the corresponding routing scheme for the proposed network. In general, a SIN is a network that is capable of achieving real-time acquisition, transmission, and processing space information using different space platforms, that is, geostationary Earth orbit (GEO) satellites, middle Earth orbit (MEO) satellites, low Earth orbit (LEO) satellites, stratospheric balloons, manned and unmanned aircraft, and so on.…”

Space information networks are proposed to broaden the observation area and realize continuous information acquisition using satellites and high-altitude platform stations. Space information networks are able to enhance detection and transmission capabilities compared to the current single Earth observation satellite. The satellite-terrestrial network is an important component of the space information networks. Hence, the major contribution of this article is to propose a new transmitted link selection scheme in a satellite-terrestrial network. Switch-and-stay combining scheme is used by destination to have a trade-off between the complexity and efficiency. The satellite, terrestrial relays, and destination user are influenced by hardware impairments, respectively. The closed-form expressions for the outage probability and throughput are derived. In order to analyze the system performance at high signal-to-noise rate, the asymptotic expressions for the system performance are also derived to give a special view on the impact of hardware impairments on the considered network. What is more, numerical results are derived to verify the correctness of our analytical results.
