Abstract

The GNSS (Global Navigation Satellite System) provides georeferenced data for many civil and military applications. Since the removal of noise in the USGPS signal in 2000, civil applications have exploded and correction methodologies have greatly improved the quality of data without additional cost. DGPS make profit of geostationary signal in order to decrease the error level from metric to sub metric range; however such decrease strongly depends upon local circumstances. In this paper we compare the quality of DGPS signal under very dissimilar conditions: North vs South hemisphere, various geoides (ED50 vs WGS84) and distance to the geostationary satellite among others. The data have been acquired during several seasons according, all of them in vine crops (permanent crop and therefore of known position) which allows to easily address the quality of the georeferenced position.
