Abstract :
This work proposes a novel method to estimate an index which summarizes the state of the satellite constellation in a Global Positioning System (GPS). Experimental results evidence that it is correlated with the localization error. An algorithm for the estimation and the correction of the GPS offset is therefore proposed. The improvement of the localization accuracy is demonstrated using an automotive, high-end GPS.
