PRESS RELEASES - Press Release - Special Report on the management of the Galileo programme's development and validation phase1. Luxembourg, 2009/06/29 Special Report on the management of the Galileo programme's development and validation phase 1 The Galileo programme was launched in the mid 1990s with the aim of establishing a European Global Navigation Satellite System. It has seen substantial delays and cost overruns. In this Special Report the European Court of Auditors analyses the development and validation phase of the programme. The audit addressed the period during which the Galileo Joint Undertaking (GJU) managed the development and validation phase, focusing in particular on its mandate, the process of setting it up and the management of its tasks. The audit findings cover the different tasks of the GJU during the development and validation phase as well as issues related to public-sector governance. The Court concluded that management of the development and validation phase was inadequate.
Finally, the report includes a number of detailed recommendations for the Commission. Testing Of Galileo Satellite Navigation System Can Begin Eurasia Review. By Eurasia Review A significant milestone in the construction of Galileo – Europe’s satellite navigation system – was achieved Friday. Two operational satellites were launched on 12 October at 18:15 UTC from Kourou, French Guiana, using a Soyuz launcher. These two new satellites, named David and Sif1, have joined another pair of satellites that has been orbiting the Earth since October 2011.
Together they form a mini-constellation of four satellites needed for Galileo’s validation and fine-tuning. Following a detailed in-orbit check, by the end of 2014 a further 14 satellites will be deployed. This will enable to provide the very first services based on this cutting-edge EU infrastructure. This market is currently valued at €124 billion and expected to increase to €250 billion by 2020. European Commission Vice President Antonio Tajani, responsible for enterprise and industry policy, said, “We have taken another step toward completing the Galileo system for European citizens and businesses. Galileo satellite navigation system to be up and running from 2014. Industry committee MEPs approved new legislation on Tuesday to ensure that Europe's two satellite navigation systems - Galileo, the European GPS system, and the EGNOS programmes for improving GPS signal quality - can be funded and operated from 2014 to 2020.
The Commission has earmarked €7.9 billion to complete the EU's satellite navigation infrastructure over the seven-year period. MEPs call in amendments to the draft legislation for more of the new services to be offered free of charge. The Public Regulated Service, which will ensure, from 2014, that key services such as police and ambulance services continue to operate in times of crisis, must be free, they say. So must the Safety of Life Service, a European Geostationary Navigation Overlay Service (EGNOS) programme, which will be fully available later and will make air navigation safer.
Background Galileo is the EU's own, independent, civilian, global satellite navigation system. Next steps. European Satellite Navigation System (GNSS): Galileo and EGNOS new steps. - 19/09/2012 - EPP Group. Press Release A legislation on the new framework for the financing and governance of the two European satellite navigation programmes Galileo (European GNSS) and EGNOS (GPS signal augmentation) for the period 2014-2020 has been adopted by the Industry, Research and Energy Committee of the European Parliament. The objective of the Galileo Programme is to create the first European global satellite navigation system built under civilian control.
The fully deployed system will consist of 30 satellites and the associated ground infrastructure. EGNOS (European Geostationary Navigation Overlay Service) has been providing improved GPS signals in Europe since 1 October 2009. "This framework for the period 2014-2020 is of key importance since first Galileo services will be offered in 2014 and the full operational capability will be reached by 2020", said Rapporteur Marian-Jean Marinescu, Vice-Chairman of the EPP Group.

Loser: No Payoff for Galileo Navigation System. Geopositioning Suppose somebody offered you a free lunch at the best restaurant in Paris, Chez Gaston, complete with your favorite wine, a 500 bottle of Château La Mondotte Saint-Emilion. Would it really make sense for you to say no thanks, and then spend millions of dollars to open your own French restaurant in New York, with the stated intention of taking away Gaston’s business within five years? This, in effect, is what Europe has been doing in the field of geopositioning, a rapidly growing multibillion-dollar business that soon will dominate all aspects of transportation and navigation and is sure to play a growing role in widely disparate activities from commercial fishing to emergency services.
The idea of a European geopositioning system similar to the U.S. Galileo’s boosters often described the system’s commercial promise in extravagant terms, taking in even seasoned and tech-savvy journalists like T.R. There remains the question of signal access. What The Experts Say T.J. GALILEO Receivers - Navipedia. From Navipedia The Galileo System will be an independent, global, European-controlled, satellite-based navigation system and will provide a number of guaranteed services to users equipped with Galileo-compatible receivers.
Basic elements of a generic GNSS Receiver are an antenna with pre-amplification, an L-band radio frequency section, a microprocessor, an intermediate-precision oscillator, a feeding source, some memory for data storage, and an interface with the user. The calculated position is referred to the antenna phase centre. Galileo receivers A Galileo Acquisition Receiver Architecture The Galileo global navigation satellite system will employ many new methods and technologies to offer superior performance and reliability. A GALILEO Receiver is a device capable of determining a navigation solution by processing the signal broadcasted by Galileo satellites. Ephemeris which are needed to indicate the position of the satellite to the user receiver. Particularities Test user segment. Satellite navigation. A satellite navigation or sat nav system is a system of satellites that provide autonomous geo-spatial positioning with global coverage.
It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to high precision (within a few metres) using time signals transmitted along a line of sight by radio from satellites. The signals also allow the electronic receivers to calculate the current local time to high precision, which allows time synchronisation. A satellite navigation system with global coverage may be termed a global navigation satellite system or GNSS. As of April 2013, only the United States NAVSTAR Global Positioning System (GPS) and the Russian GLONASS are global operational GNSSs.
Global coverage for each system is generally achieved by a satellite constellation of 20–30 medium Earth orbit (MEO) satellites spread between several orbital planes. Classification[edit] History and theory[edit] Modern systems are more direct. [edit] GPS[edit] Système de positionnement par satellites. Un article de Wikipédia, l'encyclopédie libre. Le système de positionnement par satellites, appelé sous le nom plus complet de système de positionnement et de datation par satellites ou sous son sigle anglais GNSS (Global Navigation Satellite System), est le nom général des systèmes de navigation satellitaires fournissant une couverture globale de géopositionnement à usage civil.
Les GNSS utilisent les constellations existantes de satellite de navigation, et des systèmes satellitaires complémentaires d’amélioration de performance, comme EGNOS, ou des compléments au sol, comme le DGPS. Depuis 2010, le système de satellites NAVSTAR, développé aux États-Unis, constituant le GPS, n'est plus la seule constellation totalement opérationnelle. Le système russe GLONASS, opérationnel en 1996, était devenu obsolète dans les années 2000, à cause de la chute de l'URSS, provoquant un non-entretien et un délabrement du matériel le faisant fonctionner.
Principe[modifier | modifier le code] Global Positioning System. Un article de Wikipédia, l'encyclopédie libre. Le Global Positioning System (GPS) – que l'on peut traduire en français par « système de localisation mondial » – est un système de géolocalisation fonctionnant au niveau mondial. En 2011, il est avec GLONASS, un système de positionnement par satellites entièrement opérationnel et accessible au grand public. Ce système a été théorisé par le physicien D.
Fanelli[1] et mis en place à l'origine par le Département de la Défense des États-Unis. Il est très rapidement apparu que des signaux transmis par les satellites pouvaient être librement reçus et exploités, et qu'ainsi un récepteur pouvait connaître sa position sur la surface de la Terre, avec une précision sans précédent, dès l'instant qu'il était équipé des circuits électroniques et du logiciel nécessaires au traitement des informations reçues.
