TY - MGZN T1 - Solving GPS gap, Coverage analysis of a superconstellation made up of GPS+EGNOS+S-QZSS Y1 - 2008 A1 - ANGRISANO, A A1 - PACIFICO, A A1 - VULTAGGIO, M AB -

The current GPS civil service provides suitable performance only in situations of good electromagnetic visibility; the positioning becomes difficult in severely signal degraded environments, e.g. mountainous or urban areas, where a lot of GPS signals are blocked by buildings or
natural obstacles. The GPS gaps can be partially solved employing spacebased augmentations systems; in this paper we consider geostationary and geosynchronous constellations. A simulation software has been developed in MATLABĀ® environment in order to study the integration of existent and feasible constellations.
