UNAVCO will develop, operate, and maintain a distributed, multi-user Geodetic Facility for the Advancement of GEoscience (GAGE). Geodesy characterizes the Earth's time varying shape, orientation in space, mass distribution, and gravity field. It has revolutionized the geosciences, by measuring Earth changes with unprecedented spatial and temporal resolution. The GAGE facility employs expert professional staff, with guidance provided by the scientific community, to manage and operate a set of foundational geodetic capabilities that are essential for current research support, as well as frontier geodetic activities that will enable future research. The facility will promote advances in our understanding of continental deformation; tectonic plate boundary processes; the processes that drive earthquakes, volcanic eruptions and landslide hazards; continental water storage, atmospheric, ice sheet and glacier dynamics; and interactions among these components of the Earth system. The geodetic capabilities provided through the GAGE facility contribute to issues of national/global strategic importance, including geohazard assessment and disaster resilience; environmental management and economic development; and STEM (science, technology, engineering, and mathematics) education and workforce development. Data products from GAGE will be used by federal agencies including the National Aeronautics and Space Administration, the United States Geological Survey and the National Oceanic and Atmospheric Administration, for missions including spacecraft positioning, satellite orbit, and timing corrections; earthquake, tsunami, and volcano early warning; weather forecasting; water resources; and environmental management. State departments of transportation will use GAGE data to help support traffic monitoring and control and increasingly GAGE data will support commercial sector positioning needs including for agriculture, construction and surveying, transportation (including air, rail, and maritime), mining and resource exploration, and fleet vehicle tracking. The GAGE facility will manage and operate: 1) global and regional continuously operating Global Navigational Satellite Systems (GNSS) and complementary geodetic technology networks; 2) portable geophysical instrumentation for use in principal investigator driven and community experiments; 3) geodetic instrumentation testing and support service; 3) data management systems for the collection, quality assurance, curation, management, and distribution of open access data and data products; and 4) education, workforce development, and public outreach programs that foster the development of the next generation geosciences workforce, are designed to be inclusive and enhance participation of traditionally underrepresented groups in the geosciences, and engage the public by highlighting advances in geophysical sciences and their societal relevance. Innovative and transformative research that will benefit from GAGE examines both the dynamics of individual processes and the nonlinear interactions within and among larger Earth systems. The study of active processes from geocenter motion to the studies of the lithosphere, cryosphere, hydrosphere, and atmosphere requires understanding of the coupling and feedbacks across a range of length and time scales, and between the solid Earth and its fluid envelopes, in both physical and biological environments. Under NSF, and NASA partner agency support for GAGE, UNAVCO will integrate and federate a set of currently operated but at present independently managed GNSS stations to form the Network of the Americas (NOTA). UNAVCO will modernize NOTA stations with state-of-the-art, multi-sensor, multi-GNSS, receivers with real-time streaming data and analysis. These enhancements will enable higher precision positioning than currently possible and new application of GNSS data that can be used for geohazards warning systems, study of ocean and atmosphere dynamical behavior, and observation of key environmental parameters such as water storage, soil moisture, and sea and lake-level changes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

UNAVCO 将开发、运营和维护分布式、多用户大地测量设施，以促进地球科学的发展 (GAGE)。大地测量学描述了地球随时间变化的形状、空间方向、质量分布和重力场。它以前所未有的空间和时间分辨率测量地球的变化，彻底改变了地球科学。 GAGE 设施聘用专家专业人员，在科学界提供的指导下，管理和运行一系列基础大地测量能力，这些能力对于当前的研究支持以及支持未来研究的前沿大地测量活动至关重要。该设施将促进我们对大陆变形的理解的进步；构造板块边界过程；引发地震、火山爆发和山体滑坡灾害的过程；大陆水储存、大气、冰盖和冰川动力学；以及地球系统这些组成部分之间的相互作用。通过 GAGE 设施提供的大地测量能力有助于解决具有国家/全球战略重要性的问题，包括地质灾害评估和抗灾能力；环境管理和经济发展； STEM（科学、技术、工程和数学）教育和劳动力发展。 GAGE 的数据产品将被美国国家航空航天局、美国地质调查局和国家海洋和大气管理局等联邦机构用于航天器定位、卫星轨道和定时校正等任务；地震、海啸、火山预警；天气预报；水资源；和环境管理。各州交通部门将使用 GAGE 数据来帮助支持交通监控和控制，并且越来越多的 GAGE 数据将支持商业部门的定位需求，包括农业、建筑和测量、交通（包括航空、铁路和海运）、采矿和资源勘探以及车队车辆跟踪。 GAGE 设施将管理和运营： 1) 全球和区域持续运行的全球导航卫星系统 (GNSS) 和互补的大地测量技术网络； 2) 用于主要研究者驱动和社区实验的便携式地球物理仪器； 3）大地测量仪器测试及支持服务； 3）用于开放获取数据和数据产品的收集、质量保证、策划、管理和分发的数据管理系统； 4) 教育、劳动力发展和公共宣传计划，促进下一代地球科学劳动力的发展，旨在具有包容性并加强传统上代表性不足的群体对地球科学的参与，并通过强调地球物理科学和技术的进步来吸引公众参与他们的社会相关性。受益于 GAGE 的创新和变革性研究既检查了单个过程的动力学，也检查了较大地球系统内部和之间的非线性相互作用。从地心运动到岩石圈、冰冻圈、水圈和大气层的研究，需要了解一定范围的长度和时间尺度上的耦合和反馈，以及固体地球与其流体包层之间的耦合和反馈，无论是在物理上还是在物理上。和生物环境。在 NSF 和 NASA 合作伙伴机构对 GAGE 的支持下，UNAVCO 将整合和联合一组目前运行但目前独立管理的 GNSS 站，形成美洲网络 (NOTA)。 UNAVCO 将使用最先进的多传感器、多 GNSS 接收器以及实时流数据和分析来对 NOTA 站进行现代化改造。这些增强功能将实现比目前更高精度的定位，以及 GNSS 数据的新应用，可用于地质灾害预警系统、海洋和大气动力学行为研究以及水储存、土壤湿度和海洋和大气等关键环境参数的观测。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
