Acquisition of New GPS Equipment for the UNAVCO Community Pool in Support of Current and Emerging Solid-Earth Sciences Research Applications

这笔赠款支持对NSF研究社区的全球定位系统(GPS)接收器池进行重大升级，这对高精度GPS运动测量至关重要，以支持与地球科学相关的研究。将在三年内购买30台新一代GPS接收器，保持最先进的接收器池，以确保联阿援助团设施在用于战役应用的大地GPS技术方面继续领先。新的GPS接收器将使研究界受益，其改进的功能包括更好的数据质量、更低的功耗、更小的尺寸和更大的内存。联阿援助团设备池的主要用途仍然是传统的毫米级精密地壳形变全球定位系统活动，每个调查点需要收集数天的数据，24个新的接收器专门用于这种支助。另外六个具有额外能力的接收器还将支持需要厘米级精度的动态、快速静态和实时动态应用。随着新设备可用于池中使用，目前的池接收器将逐步退出池中，并纳入NSF资助的研究项目，用于永久GPS安装。*

Thirty new generation GPS receivers will be purchased over three years, maintaining a state-of-the-art receiver pool that ensures the UNAVCO Facility's continued leadership in geodetic GPS technology for campaign applications. The new GPS receivers will benefit the research community with improved features including better data quality, reduced power consumption, smaller size, and increased memory. The main use of the UNAVCO equipment pool continues to be traditional millimeter-level precision crustal deformation GPS campaigns involving data collection for several days per survey point, and 24 new receivers are dedicated to such support. An additional six receivers with added capability will also support kinematic, rapid static, and real-time kinematic applications that require centimeter-level precision. As new equipment becomes available for pool use, the current pool receivers will be phased out of the pool and into NSF funded research projects for use in permanent GPS installations.***
