PROCEDE ET SYSTEME D'AUGMENTATION DE LA DISPONIBILITE D'UN SYSTEME DE GEOLOCALISATION PAR SATELLITE

摘要

The system has a measuring system (3) for measuring a signal emitted by a global positioning system (1). A processing station (4) receives measurement transmitted by the measuring system. An indicator indicates a gap between a comportment model and a real comportment of the global positioning system. A distortion model ensures distortion of code snippet transmitted to a positioning receiver (2) by navigation satellite. The distortion model ensures distortion of phase of signal transmitted to the receiver by the navigation satellite.
