Support of UNAVCO Community and Facility Activities

0321760 prescott在空间和时间上密集的GPS观测正在导致地球科学的根本性新发现，这些发现对我们对全球和区域板块构造相互作用的理解产生了巨大影响，并对减轻世界人口稠密地区的地震和火山灾害具有重要意义。通过这项合作协定提供的支助将在四年期间内管理和运作联安援助团国家全球定位系统支助设施。UNAVCO设施历来提供集中支持，协助地球科学界获取、存档、分发和应用高精度GPS数据，通过美国国家科学基金会和美国国家航空航天局的支持研究固体地球过程和危害。设施运营的管理责任将由UNAVCO， Inc.负责，该公司是最近成立（2001年4月）的独立501(c)(3)非营利性研究组织。联安援助团管理的设施将在全球定位系统促进的地球科学研究的所有阶段向研究人员提供援助，包括：规划；设备选择和设备贷款和/或必要设备的采购和预算协助；为永久、连续运行网络（CGPS）或GPS基准的离散战役式职业的GPS接收器的纪念碑和调试提供后勤和现场工程支持；技术开发活动；以及数据安全、质量控制、检索、归档和分析。该设施还将支持NASA/固体地球和自然灾害（SENH）项目活动，并在监测和维护NASA GPS全球网络（GGN）的一个子集方面发挥关键作用。在后者方面，联阿援助团的设施将为国际全球定位系统服务网内大量台站的持续运作提供维修和安全保障。IGS网络为全球GPS用户提供基准站、轨道和时钟估计。设施领导是地球科学领域高精度GPS研究的倡导者和技术顾问。该基金将支持社区参与该基金的治理和运营，具体方式包括：社区年度会议；指导委员会会议和重点科学讲习班的支持。教育和外展活动将包括增加一名全职的教育和外展协调员，并制定学生实习计划。UNAVCO, Inc.的设施和管理结构为NSF和NASA提供了一个单一的接触点，允许对设施资源进行有效和负责任的管理。NASA对该设施的支持将通过NSF进行年度机构间转移。＊＊＊

0321760PrescottDense GPS observations in space and time are resulting in fundamental new discoveries in the earth sciences, discoveries that have an enormous impact on our understanding of global and regional plate tectonic interactions and have implications for mitigating earthquake and volcanic hazards in densely populated regions of the world. Support through this cooperative agreement will provide for the management and operation of the UNAVCO national Global Positioning System (GPS) support facility over a period of four years. The UNAVCO facility has historically provided centralized support to assist the geosciences community with the acquisition, archival, distribution, and application of high-precision GPS data to study solid-Earth processes and hazards through NSF and NASA support. Management responsibility for facility operations will be under UNAVCO, Inc., a recently incorporated (April 2001) and independent 501(c)(3) non-profit research organization.The UNAVCO, Inc. managed facility will provide assistance to researchers in all phases of GPS-facilitated geosciences research including: planning; equipment selection and equipment loans and/or procurement and budgeting assistance for necessary equipment; logistics and field engineering support for the monumentation and commissioning of GPS receivers in either permanent, continuously operated networks (CGPS) or discrete campaign-style occupations of GPS benchmarks; technology development activities; and data security, quality control, retrieval, archiving and analysis. The facility will also support NASA/Solid Earth and Natural Hazards (SENH) program activities and plays a crucial role in monitoring and maintaining a subset of NASA's GPS Global Network (GGN). In the latter, the UNAVCO facility will provide maintenance and security for the continuous operation of a large number of stations within the International GPS Service (IGS) network. The IGS network provides fiducial stations, orbits, and clock estimates for GPS users worldwide. Facility leadership serves as an advocate and technology advisor for high precision GPS research in the earth sciences. The facility will support community involvement in the governance and operation of the facility through providing support for interactions including: an annual community meeting; meetings of the steering committees and support of focused scientific workshops. Educational and outreach (E&O) activities will include the addition of a full time E&O Coordinator and the development of a student intern program. The UNAVCO, Inc. facility and management structure provide NSF and NASA with a single point of contact that allows for effective and accountable management of facility resources. NASA support of this facility will occur via annual interagency transfers through NSF. ***
