The HAS will be based on the provision of PPP corrections (orbit, clock, biases, atmospheric corrections), at a maximum rate of 448 bps per Galileo satellite connected to an uplink station, allowing the user to obtain a horizontal positioning error of less than two decimetres (95 %) in nominal conditions of use. The parameters and the business model of the service will foster innovation in both consolidated and emerging markets, notably in key areas such as drones and autonomous cars, minimising disruption in the current business models of established providers. The HAS will be implemented in three phases, including testing and experimentation; an initial Galileo High Accuracy Service for a reduced number of signals, with relaxed performance targets and a reduced coverage area; and a full Galileo HAS that will offer two service levels and global coverage. Service Level 1 will provide PPP corrections globally to achieve 20 cm horizontal precision with Note de contenu : 1- Introduction 2- Target markets 3- HAS service characterisation 4- HAS high level architecture 5- HAS roadmap 6- HAS relevant documentation and interfaces avialable 7- Summary Numéro de notice : 28526 Affiliation des auteurs : non IGN Thématique : POSITIONNEMENT Nature : Plaquette / brochure DOI : sans En ligne : https://www.gsa.europa.eu/newsroom/news/gsa-publishes-high-accuracy-service-info [...] Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=97339
