ECS-0636519M. Win, MITWe propose a hybrid satellite/terrestrial system for seamless localization and communication, in which satellite links serve as a backbone for communication, while GPS provides positioning references for the terrestrial anchor nodes. UWB transmission between terrestrial nodes (anchors and GPS-denied agents) enables accurate localization and robust wireless communication in situations where narrowband techniques may fail. The combination of these technologies in a hybrid network will extend the localization and communication capabilities beyond the boundaries of current systems.ResearchThis project aims to develop basic research in support of seamless location-awareness and communication for large, dynamic networks. To achieve this objective, we will: . formulate an analytical framework for cooperative localization;. develop localization algorithms suitable for dynamically changing networks; . determine optimal anchor node placement strategies under different constraints; and . investigate optimum combining methods for anchor and satellite relay diversity. Education Primary educational goals are to integrate research results into graduate coursework and to further develop the multidisciplinary laboratory at MIT. Intellectual MeritThis research will enable the design and analysis of efficient distributed algorithms for cooperative UWB technologies, optimal anchor placement, and satellite relay diversity techniques. It will additionally provide novel methodologies for the fundamental understanding of hybrid satellite/terrestrial networks.Broader ImpactsThis research will facilitate new technologies for future wireless networks. The framework and methodologies will be integrated into standardization efforts, teaching materials, and textbooks. This project will create a cadre of engineers, including women and minorities, who will help develop and operate future hybrid systems.

ECS-0636519M。 Win，麻省理工学院我们提出了一种用于无缝定位和通信的混合卫星/地面系统，其中卫星链路作为通信的骨干网，而GPS为地面锚节点提供定位参考。地面节点（锚点和 GPS 拒绝代理）之间的 UWB 传输可以在窄带技术可能失败的情况下实现准确的定位和强大的无线通信。这些技术在混合网络中的结合将把定位和通信能力扩展到当前系统的边界之外。研究该项目旨在开展基础研究，以支持大型动态网络的无缝位置感知和通信。为了实现这一目标，我们将： .制定合作本地化的分析框架；开发适合动态变化网络的定位算法； 。确定不同约束下最优的锚节点放置策略；和 。研究锚点和卫星中继分集的最佳组合方法。教育 主要教育目标是将研究成果整合到研究生课程中，并进一步发展麻省理工学院的多学科实验室。智力价值这项研究将能够设计和分析用于协作 UWB 技术、最佳锚点放置和卫星中继分集技术的高效分布式算法。它还将为从根本上理解混合卫星/地面网络提供新颖的方法。更广泛的影响这项研究将促进未来无线网络的新技术。该框架和方法将纳入标准化工作、教材和教科书。该项目将培养一支包括女性和少数族裔在内的工程师骨干队伍，他们将帮助开发和运营未来的混合动力系统。
