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.***

0214355JohnsThis赠款支持一个重大的升级，以美国国家科学基金会研究界的全球定位系统（GPS）接收器池，高精度的GPS运动测量，以支持地球科学相关的研究至关重要。将在三年内购买30个新一代全球定位系统接收器，以维持最先进的接收器库，确保联刚特派团设施在运动应用的大地定位系统技术方面继续保持领先地位。新的GPS接收机将有利于研究界的改进功能，包括更好的数据质量，降低功耗，更小的尺寸，并增加内存。联合国志愿人员组织设备库的主要用途仍然是传统的毫米级精确地壳变形全球定位系统活动，涉及在每个测量点收集数天的数据，24个新接收器专门用于这种支助。另外六台具有额外功能的接收机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。随着新设备可用于游泳池，目前的游泳池接收器将逐步退出游泳池，并进入NSF资助的研究项目，用于永久性GPS安装。
