“…Hartenstein and Stephens [77] discussed space explorations from the perspective of information systems; they found it was most critical to develop integrated and effective information systems for successful space exploration missions. The variants of mobility, load, time delay of space objects brought the problems and challenges in transmitting data in connecting space objects to the ground [95].…”

“…Developing a space wireless network requires the technologies for power supplies, wireless radio frequencies, communication protocols, and verification and valuations [113]; while the wireless networks by satellites have shown their limitations in inflexible network topologies, unstable quality of transmission, delays of transmission, high-bit error rates and poor connectivity. A satellite network can be characterized at the aspects of architecture, collaboration strategy and operating frequency [95]. The topology of a satellite network was dynamic and link lengths and on-off model are changed over time, satellite nodes should support a relay cooperation in multipoint interactions.…”

This paper aims to present a comprehensive survey on information integration (II) in space informatics. With an ever-increasing scale and dynamics of complex space systems, II has become essential in dealing with the complexity, changes, dynamics, and uncertainties of space systems. The applications of space II (SII) require addressing some distinctive functional requirements (FRs) of heterogeneity, networking, communication, security, latency, and resilience; while limited works are available to examine recent advances of SII thoroughly. This survey helps to gain the understanding of the state of the art of SII in sense that (1) technical drivers for SII are discussed and classified; (2) existing works in space system development are analyzed in terms of their contributions to space economy, divisions, activities, and missions; (3) enabling space information technologies are explored at aspects of sensing, communication, networking, data analysis, and system integration; (4) the importance of first-time right (FTR) for implementation of a space system is emphasized, the limitations of digital twin (DT-I) as technological enablers are discussed, and a concept digital-triad (DT-II) is introduced as an information platform to overcome these limitations with a list of fundamental design principles; (5) the research challenges and opportunities are discussed to promote SII and advance space informatics in future.INDEX TERMS Information integration (II), space informatics, digital triad (DT-II), internet of digital-triad things (IoDTT), first-time right (FTR), space information integration (SII).

“…On the other hand, it reduces the resource consumption of a single satellite and improves the overall viability of the satellite network. Therefore, inter-satellite cooperative technology has now been widely discussed and has broad application prospects [18]- [20]. However, considering the dynamic and random task queues in a realistic scenario, it leads to a huge state and action space of the satellite MEC system enabled by cooperative computing.…”
