GPS Geodetic Receivers - A Cost-Sharing Instrumentation Purchase Proposal

该奖项提供了一半的资金， 三个全球定位系统（GPS）接收器，其用途将是 拉蒙特-多尔蒂地质研究所的科学家们 哥伦比亚大学天文台和大学导航星 联合会（联安核查团）。哥伦比亚将提供剩余的资金 购买仪器所需的费用， 为仪器提供维护和维修服务 包装件. GPS接收机能够快速准确地进行大地测量， 误差小于基线一厘米的测量 数百公里，并将用于各种 板块构造与地震相关研究项目 问题研究

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.
