RENAG-DC

Within the RESIF-EPOS observation research infrastructure and the Action Spécifique RESIF-GNSS action, the Reseau National GNSS permanent (RENAG) is the network of GNSS observation stations of French universities and research organizations. It is currently composed of 85 GNSS stations (Global Navigation Satellite System such as GPS, GLONASS, Galileo). The scientific objectives of RESIF-RENAG range from the quantification of the slow deformation in France to the sounding of the atmosphere (troposphere and ionosphere), through the measurement of sea-level variations and the characterization of transient movements related to overloads. Data production is carried out in a distributed way by the laboratories and organizations that manage the stations. 12 teams are specifically in charge of station maintenance and of accurately filling in the metadata files. A single data center, RENAG-DC, hosted at the Observatoire de la Côte d'Azur (OCA) within the Geoazur laboratory, is in charge of data management, from their collection to their distribution in the standard RINEX format (http://renag.resif.fr).

在RESIF-EPOS观测研究基础设施以及RESIF-GNSS专项行动的框架下，Reseau National GNSS permanent（RENAG）构成了法国大学和研究机构的GNSS观测站网络。目前，该网络由85个GNSS站（全球导航卫星系统，如GPS、GLONASS、Galileo）组成。RESIF-RENAG的科学目标涵盖从法国缓慢形变的量化到大气层（对流层和电离层）的探测，包括海平面变化的测量以及对超载相关瞬时运动的表征。数据生产由管理各站点的实验室和组织以分布式的方式进行。共有12个团队专门负责站点的维护和精确填写元数据文件。位于蔚蓝海岸天文台（OCA）Geoazur实验室内的单一数据中心，RENAG-DC，负责数据管理，从数据的收集到以标准RINEX格式（http://renag.resif.fr）的分布。
