SAPOS NW Real-time Positioning Service (EPS)

The satellite positioning service of the German national survey SAPOS offers comprehensive access to official spatial reference through centimeter-accurate positioning via GNSS (Global Navigation Satellite Systems) in the ETRS89 reference system. The satellite positioning service of the German national survey SAPOS is based on a network of reference stations that permanently evaluate satellite signals from the Global Positioning System (GPS) and Russian Globalnaya nawigazionnaya sputnikovaya Sistema (GLONASS). The corrective data for the Global Navigation Satellite Systems (GNSS) are provided for differential GNSS measurement methods. SAPOS®-EPS enables real-time position determination with a position accuracy of 0.3 m to 0.8 m and a height accuracy from 0.5 m to 1.5 m.德国国家测绘局的卫星定位服务SAPOS，可通过基于ETRS89参考系统的GNSS（全球导航卫星系统，Global Navigation Satellite Systems）实现厘米级定位，全面提供官方空间参考基准的接入能力。该SAPOS卫星定位服务基于参考站网络构建，该网络可持续解算来自全球定位系统（GPS，Global Positioning System）与俄罗斯格洛纳斯系统（GLONASS，Globalnaya nawigazionnaya sputnikovaya Sistema）的卫星信号。针对差分GNSS测量方法，该服务可提供GNSS校正数据。SAPOS®-EPS支持实时位置解算，其平面定位精度为0.3米至0.8米，高程精度为0.5米至1.5米。
