Depending on the user application, EuroNet calls additional, external software modules responsible for data processing, modelling and statistical computations. The Alberding GNSS Status software has a variety of external modules, e.g. DGNSS/RTK positioning, real-time or post-processed PPP positioning, L1 VRS networking and real-time PPP-based troposphere modelling. Customer provided executables can also be integrated into the monitoring system.
