WARTK based on EGNOS and Galileo: technical feasibility study (WARTK-EGAL). The main goal of the WARTK-EGAL project is to show the capability of using the EGNOS reference station network for supporting wide-area sub-decimetre error level navigation over the EGNOS service area with GPS/Galileo signals. The main techniques supporting this new approach are related to an accurate real-time computation of ionospheric corrections, combined with an optimal processing of GNSS observables (carrier phases in particular) in both 2 and 3-frequency systems. This is the so-called WARTK technique, previously developed by gAGE/UPC and protected by two patents.
