EGNOS ESTB field tests in static and kinematic modes

Abstract

EGNOS (European Geostationary Navigation Overlay System) ESTB (EGNOS System Test Bed) static and kinematic tests were performed in order to analyse the signal transmission capabilities coming from the lnmarsat Geostationary Satellite PRN120. The data were stored in the Stand-alone mode and compared with the a priori known co-ordinates of the control point used for the experiment, or with the post-processed phase data relative to the same point. The results demonstrate that EGNOS, even though enhancing the accuracies with respect to the Standalone positioning, cannot completely meet the required standards yet
