[Termes IGN] performanceRésumé : (Auteur) This summer, after more than 8 years of intensive work by ESA and European industry, the European Geostationary Overlay Service (EGNOS) achieved two major programme milestones, with the successful completion of the formal technical-qualification process (Operational Readiness Review) and the start of initial operations. The measured performance of the system has already been shown to exceed requirements in several respects.
Via the EGNOS project, the European Tripartite Group - constituted by ESA, the European Commission and Eurocontrol -has implemented the European contribution to the first-generation Global Navigation Satellite System (GNSS-1). ESA has been responsible for the system design, development and qualification of the advanced operational system, also known as EGNOS V1.
In parallel with the start of operations, the EGNOS system will now be enhanced to enlarge the service area, to provide additional services, to further improve performance and to follow the global evolution in Satellite-Based Augmentation Systems (SBAS) that is taking place, leading up to the introduction of the European Galileo system.Numéro de notice : A2005-488 Affiliation des auteurs : non IGN Thématique : IMAGERIE/POSITIONNEMENT Nature : Article DOI : sans En ligne : http://www.esa.int/esapub/bulletin/bulletin124/bul124i_gauthier.pdf Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=27624

[Termes IGN] télécommunication sans filRésumé : (Auteur) Over the last 20 years, major developments have taken place in parallel in the key technology areas of wireless communications ad satellite navigation. Both are gradually becoming indispensable tools in the professional and consumer worlds. Nowadays, major synergies are developing in terms of wireless mobile terminals with a navigation capability, or navigation terminals with wireless communications capabilities. ESA is undertaken a series of activities to support the exploitation of such synergies for the benefit of Europe's citizens through the provision of new and upgraded services from space.

[Termes IGN] télécommunication sans filRésumé : (Auteur) Satellite-based augmentation systems (SBAS), like GPS, suffer visibility limitations in urban settings. A prototype receiver combines EGNOS correction messages received through a wireless Internet connection with pseudorange measurements from its internal GPS receiver, delivering a significant improvement in positioning accuracy and availability.
