Untersuchungen zu EGNOS - Ergebnisse von Messungen während der Testphase

摘要

EGNOS signifies European Geostationary Navigation Overlay Service and is a service provided by ESA for users of GPS and GLONASS in cooperation with other European organisations. EGNOS supplies geostationary satellite correction data for satellite orbits and satellite clock and for atmospheric influence (ionospheric, tropo-spheric), in order to guarantee an improved positioning on DGPS measurements. Furthermore, this service sends a so-called integration signal giving information on the system's state of affairs. EGNOS will be operable at the end of 2005 full according to the providers. The present article gives an overview on the concept, of EGNOS as well as the method of ist usage. Results and achieved measurement accuracies during the testing phase of EGNOS (ESTB) will be presented and will give an insight into the usage potential of this DGPS method. The investigations are subject of the dissertation by Dominik Mueller, at the advanced technical college in Mainz, Germany, geographical informatics and measuring department, which was written in cooperation with the department of Geoinformationswesen of the German armed forces.%EGNOS (European Geostationary Navigation Overlay Service) stell dem Nutzer von GPS und GLONASS Korrekturdaten über geostationäre Satelliten zur Verfügung, so dass dieser über DGPS eine verbesserte Positionsbestimmung durchführen kann.
