Facilities Support: SOPAC GNSS Infrastructure and Real-time Operations

该拨款支持斯克里普斯轨道和永久阵列中心（SOPAC）为期四年的设施运行。方案咨委会的活动包括收集、存档和传播目前联安援助团档案无法获得的全世界约800个GPS站的资料。此外，SOPAC作为国际全球导航卫星系统（GNSS）网络的全球分析中心，提供每日GPS卫星轨道校正，通过改进参考系确定，使全球大地测量学研究受益。SOPAC活动还支持需要精确（实时和后处理）定位和参考系统数据的非学术用户，包括政府机构、商业部门、地方、州、联邦和国际机构（例如，测量、GIS、农业、智能交通、工程基础设施）。* * *

1400901BockThis grant supports facility operations of the Scripps Orbit and Permanent Array Center (SOPAC) over a four year period. SOPAC activities include the collection archiving and dissemination of some 800 GPS stations worldwide that are not currently available through the UNAVCO archive. In addition SOPAC provides daily GPS satellite orbit corrections as Global Analysis Center for the International Global Navigation Satellite System (GNSS) Network that benefit geodetic studies worldwide through improved reference frame determinations. SOPAC activities also support non-academic users requiring precise (real-time and post-processed) positioning and reference system data including government agencies, the commercial sector, and local, state, federal, and international agencies (e.g., surveying, GIS, agriculture, intelligent transportation, engineering infrastructure). ***
