TCHCS: Hybrid Satellite/Terrestrial Network for Seamless Localization and Communication

ECS-0636519 M。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，而GPS为地面锚节点提供定位参考。在窄带技术可能失败的情况下，地面节点（锚点和GPS拒绝代理）之间的UWB传输能够实现精确的定位和鲁棒的无线通信。这些技术在一个混合网络的组合将扩展超出当前systems.ResearchThis项目的边界的本地化和通信能力，旨在开发基础研究，支持无缝的位置感知和大型，动态网络的通信。为达致这个目标，我们会：制定合作本地化的分析框架;。开发适用于动态变化网络的定位算法;。确定不同约束下的最优锚节点放置策略;以及.研究锚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融入研究生课程，并进一步发展麻省理工学院的多学科实验室。智能MeritThis研究将使有效的分布式算法的设计和分析，合作UWB技术，最佳锚放置，和卫星中继分集技术。它还将提供新的方法，为混合卫星/地面网络的基本理解。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。该项目将培养一批工程师，包括妇女和少数民族，他们将帮助开发和操作未来的混合动力系统。

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.
