The field of LEO satellite constellations and GNSS is experiencing significant developments, driven by the need for sustainable, efficient, and robust space-based 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. These innovations are paving the way for more comprehensive and resilient space-based architectures. Noteworthy papers include: Sustainability or Survivability? Eliminating the Need to Choose in LEO Satellite Constellations, which proposes a paradigm shift in LSN research, and Joint Contact Planning for Navigation and Communication in GNSS-Libration Point Systems, which introduces a Joint CPD scheme for integrated constellations.
