This award provides support to the University Navstar Consortium (UNAVCO) located in Boulder, Colorado. UNAVCO is a consortium of 30 U.S. universities that manages a facility providing equipment and logistical assistance to earth scientists making use of the Global Positioning System (GPS) satellites for research in crustal dynamics, earthquake, volcano, and global change research. Using GPS, vector baselines between receivers separated by 100 kilometers or more are now being routinely measured with one centimeter (or 100 parts per billion) accuracy. Such measurements can be completed using portable equipment in a few hours or less. The ability to make such measurements has found immediate applications in research on global plate tectonics, earthquake mechanics, volcano monitoring, and regional tectonics. The UNAVCO facility offers a complete support program for university-based investigators including assistance in planning filed work, training of personnel, equipment, shipping, customs, field operations, technical troubleshooting, data management, analysis and archiving. UNAVCO also represents the academic research community and acts as a central clearinghouse for information on the scientific applications of GPS. As a part of its service to investigators, UNAVCO tests GPS equipment and techniques, and works to improve GPS surveying accuracy.

该奖项为位于科罗拉多州博尔德市的大学航星联盟(UNAVCO)提供支持。UNAVCO是由30所美国大学组成的联盟，管理着一个设施，为利用全球定位系统(GPS)卫星进行地壳动力学、地震、火山和全球变化研究的地球科学家提供设备和后勤援助。使用GPS，相距100公里或更远的接收器之间的矢量基线现在可以常规地以1厘米(或十亿分之100)的精度进行测量。这样的测量可以使用便携式设备在几个小时或更短的时间内完成。这种测量能力在全球板块构造、地震力学、火山监测和区域构造研究中立即得到应用。联阿援助团设施为驻大学的调查人员提供完整的支持方案，包括协助规划实地工作、培训人员、设备、航运、海关、现场作业、技术故障排除、数据管理、分析和存档。联阿援助团还代表学术研究界，充当全球定位系统科学应用信息的中央信息交换中心。作为向调查人员提供服务的一部分，联航防务公司测试GPS设备和技术，并致力于提高GPS测量精度。
