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

0214355johns这笔拨款支持对美国国家科学基金会研究界的全球定位系统（GPS）接收器池进行重大升级，这对于支持地球科学相关研究的高精度GPS运动测量至关重要。将在三年内购买30台新一代GPS接收机，保持最先进的接收机库，确保联安援助团设施在战役应用的大地测量GPS技术方面继续保持领先地位。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。联阿援助团设备库的主要用途仍然是传统的毫米级精确地壳变形GPS运动，涉及在每个调查点收集数天的数据，24台新接收机专门用于这种支助。另外六个具有附加功能的接收器还将支持需要厘米级精度的运动学，快速静态和实时运动学应用。随着新的设备可供池使用，目前池中的接收器将逐步退出池，并进入NSF资助的研究项目，用于永久性GPS装置

0214355JohnsThis grant supports a major upgrade to the NSF research community's Global Positioning System (GPS) receiver pool, critical for high-precision GPS campaign measurements to support Earth sciences related research. 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.***
