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.

联刚特派团将开发、操作和维持一个分布式、多用户的促进地球科学大地测量设施。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变化，从而彻底改变了地球科学。全球大地测量数据中心设施雇用专业人员，在科学界的指导下，管理和运作一套基本的大地测量能力，这些能力对目前的研究支助以及有助于今后研究的前沿大地测量活动至关重要。该设施将促进我们进一步了解大陆变形;构造板块边界过程;驱动地震、火山爆发和山崩灾害的过程;大陆水储存、大气、冰盖和冰川动态;以及地球系统这些组成部分之间的相互作用。通过全球大地测量和地理信息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;以及STEM（科学、技术、工程和数学）教育和劳动力发展。GAGE的数据产品将被包括国家航空航天局、美国地质调查局和国家海洋和大气管理局在内的联邦机构用于航天器定位、卫星轨道和定时校正;地震、海啸和火山预警;天气预报;水资源;以及环境管理等任务。国家交通部门将使用GAGE数据来帮助支持交通监测和控制，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，运输（包括航空，铁路和海运），采矿和资源勘探以及车队车辆跟踪。该设施将管理和运作：⑴全球和区域持续运行的全球导航卫星系统和补充大地测量技术网络; ⑵便携式地球物理仪器，供主要研究员驱动的实验和社区实验使用; ⑶大地测量仪器测试和支助服务; 3）数据管理系统，用于收集、质量保证、策展、管理和分发开放获取数据和数据产品;以及4）促进下一代地球科学工作人员发展的教育、工作人员发展和公共宣传计划，旨在包容和加强传统上代表性不足的群体对地球科学的参与，并通过突出地球物理科学的进步及其社会意义来吸引公众。创新和变革性的研究，将受益于GAGE检查两个单独的过程和更大的地球系统内和之间的非线性相互作用的动态。从地心运动到岩石圈、冰冻圈、水圈和大气层的活动过程的研究，需要了解在物理和生物环境中，固体地球与其流体包层之间在一系列长度和时间尺度上的耦合和反馈。在美国国家科学基金会和美国航天局伙伴机构对全球导航卫星系统地理信息系统的支持下，联合国航空航天志愿人员组织将把一组目前正在运行但目前独立管理的全球导航卫星系统台站合并并联合起来，以形成美洲网络。联合国志愿人员组织将使NOTA台站现代化，配备最先进的多传感器、多全球导航卫星系统、实时数据流和分析接收器。这些改进将使定位精度高于目前的可能性，并使全球导航卫星系统数据的新应用能够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、海与湖，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评估被认为值得支持。影响审查标准。
