Network of GNSS Stations of Castilla y León

The GNSS Network is a free and free public service of high-precision positioning with GNSS (Satellite Navigation Systems) receivers within the territory of Castilla y León in ETRS89 datum. The system provides code and phase corrections for GPS and GLONASS navigation systems, both in real time (RTK DGPS correction, through the RTCM standard), and in post-processing through RINEX files.本全球导航卫星系统（GNSS，Satellite Navigation Systems）基准站网是一项免费的公共高精度定位服务，部署于卡斯蒂利亚-莱昂自治区境内，采用ETRS89基准面，依托GNSS接收机提供服务。该系统可为全球定位系统（GPS）与格洛纳斯导航系统（GLONASS）提供码修正与相位修正服务，支持两种服务模式：实时模式下可通过RTCM标准输出RTK差分GPS修正量，后处理模式下可通过RINEX文件完成相关修正服务。
