The fields of LEO satellite constellations, GNSS, wireless communication, and integrated sensing and communication (ISAC) are experiencing significant developments. A common theme among these areas is the pursuit of sustainable, efficient, and robust systems. Researchers are exploring novel design approaches, such as sun-synchronous orbits and hierarchical collaborative content caching, to reduce the number of satellites required and minimize latency. Additionally, advancements in data transport protocols, navigation software, and contact planning are enabling more precise and reliable positioning, navigation, and timing services.
In wireless communication, researchers are moving towards more adaptive and integrated systems. New techniques, such as adaptive environment-aware processing and joint communication and sensing, are being developed to enhance the performance of communication systems. Notable papers include proposals for adaptive environment-aware transformer autoencoders, polarization-aware direction-of-arrival detection schemes, and deep learning-based receiver architectures.
The integration of emerging technologies, such as reconfigurable intelligent surfaces (RISs), aerial RISs, and active stacked intelligent metasurfaces (ASIMs), is also being explored to enhance energy and spectral efficiency. Researchers are investigating the use of these technologies in various applications, including satellite-terrestrial edge computing networks, vehicular visible light communication systems, and internet of things (IoT)-cellular networks.
In ISAC, researchers are addressing critical challenges in low-altitude wireless networks and 6G systems. Innovative solutions, such as game-based frameworks and neuro-symbolic attack detection methods, are being developed to mitigate the impact of malicious attacks on ISAC performance. Dedicated detectors that can effectively exploit signaling resources assigned to random data payloads are also being explored to enable reliable target detection in bistatic settings.
Overall, these developments are paving the way for more comprehensive and resilient space-based architectures, as well as more efficient and adaptive wireless communication systems. As research in these areas continues to evolve, we can expect to see significant advancements in the coming years.
