Acquisition of Two Global Positioning System Receivers for Geodetic and Geodynamics Research

该合同为购买两台Trimble 4000SSE双频大地测量接收机和相关现场设备提供了28,000美元，占成本的49%。德克萨斯大学奥斯汀分校将提供其中51%的费用。这两个接收器将成为联阿援助团的一部分，每年供外部研究人员使用最多6个月。联阿援助团的参与也提供技术和维修支助。这两台新接收机将补充目前通过联阿援助团提供的两台UT Austin Trimble 4000SSE接收机，每年最多使用3个月。现有的两个接收器是用德克萨斯大学当地的资金购买和升级的。新的接收器需要支持德克萨斯大学地质科学和航空航天工程系的研究生和本科生的各种教育和研究项目，并通过有组织的研究单位，包括空间研究中心、地球物理研究所和经济地质局，扩大GPS活动。这些接收器将用于本科生和研究生的有组织的教学活动和大地测量学课程，为工程和地球科学专业的学生提供必要的GPS培训。研究应用包括开发先进的GPS数据处理方法，监测包括南太平洋和南里约热内卢大裂谷在内的地区的活动构造，监测墨西哥湾海岸线变化，以及为各种地质和地球物理野外项目提供精确导航。＊＊＊

9506778 Wilson This award provides $28,000 as 49% of the costs of acquiring two Trimble 4000SSE dual frequency geodetic receivers and associated field equipment. The University of Texas at Austin will provide 51% of these costs. These two receivers will become part of the UNAVCO pool, available to outside researchers for up to 6 months each year. UNAVCO participation provides technical and repair support as well. The two new receivers will supplement two existing UT Austin Trimble 4000SSE's currently available through the UNAVCO pool for up to 3 months each year. The two existing receivers were purchased and upgraded entirely with University of Texas local funds. The new receivers are required to support expanding GPS activities in a variety of graduate and undergraduate educational and research programs at the University of Texas within the Departments of Geological Sciences and Aerospace Engineering, and through organized research units including the Center for Space Research, Institute for Geophysics, and Bureau of Economic Geology. The receivers will be used in organized instructional activities in both undergraduate and graduate field and geodesy courses to provide essential GPS training to students in engineering and earth sciences. Research applications include development of advanced GPS data processing methods, monitoring of active tectonics in areas which include the South Pacific and southern Rio Grande Rift, monitoring Gulf of Mexico shoreline changes, and providing precise navigation for a variety of geological and geophysical field programs. ***
