GPS Geodetic Receivers - A Cost-Sharing Instrumentation Purchase Proposal

该合同提供购买三个全球定位系统(GPS)接收器所需资金的一半，这些接收器将由哥伦比亚大学Lamont-Doherty地质天文台的科学家和大学NAVSTAR联盟(UNAVCO)的科学家共享使用。哥伦比亚将提供购买仪器所需的剩余资金，联阿援助团将为仪器包提供保养和维修服务。GPS接收器能够快速准确地进行大地测量，在数百公里的基线上误差小于1厘米，并将用于与板块构造和地震研究有关的各种研究项目。

This award provides one-half the funds required to acquire three Global Positioning System (GPS) receivers whose use will be shared between scientists at the Lamont-Doherty Geological Observatory of Columbia University and the University NAVSTAR Consortium (UNAVCO). Columbia will provide the remaining funds needed for the purchase of the instruments and UNAVCO will provide maintenance and repair services for the instrument packages. The GPS receivers are capable of rapid and accurate geodetic measurements with errors of less than a centimeter over baselines of hundreds of kilometers and will be used in a variety of research projects related to plate tectonics and earthquake studies.
