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

9506778威尔逊本合同提供28,000美元，作为购买两台Trimble 4000SSE双频大地测量接收机和相关野外设备所需费用的49%。德克萨斯大学奥斯汀分校将提供这些费用的51%。这两个接收器将成为联阿援助团人才库的一部分，每年向外部研究人员提供长达6个月的时间。联阿援助团的参与还提供了技术和维修支助。这两个新的接收器将补充两个现有的UT Austin Trimble 4000SSE，目前可通过联防部队池购买，每年最长可达3个月。现有的两个接收器完全是用德克萨斯大学的当地资金购买和升级的。新的接收器被要求支持在德克萨斯大学地质科学系和航空航天工程系的各种研究生和本科生教育和研究项目中扩大GPS活动，并通过空间研究中心、地球物理研究所和经济地质局等有组织的研究单位来支持。接收器将用于本科生和研究生实地和大地测量学课程的有组织的教学活动，为工程和地球科学方面的学生提供基本的全球定位系统培训。研究应用包括开发先进的GPS数据处理方法，监测南太平洋和南里奥格兰德裂谷地区的活动构造，监测墨西哥湾海岸线的变化，并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. ***
