The European programme for global navigation, positioning and timing satellite services
The EU Transport Council decision on 26 March marked a major milestone for Galileo. Though a great relief for all actors involved, in essence, this decision only set the beginning of a long journey. Europe still needs to discover how this unique project, bringing together the European Union and the European Space Agency, will revolutionise society and open a new era in the development of a new generation of global services. Europe has decided to become involved in what will become one of the main sectors of industry in the twenty-first century. The real impact of satellite navigation on society... (read more)

Galileo Satellite Transmitted Signal

Europe’s fifth Galileo satellite, one of two delivered into an incorrect orbit by the VS09 Soyuz-Fregat launcher in August, transmitted its first navigation signal in space on Saturday, 29 November 2014. It has reached its new target orbit and its navigation payload has been successfully switched on. A detailed test campaign is underway now that the satellite is in a more suitable orbit for navigation purposes. The fifth and sixth Galileo satellites, launched together on 22 August, ended up in an elongated orbit travelling up to 25,900km above Earth and back down to 13,713km. A total of 11 manoeuvres were... (read more)

Galileo Clocks under Investigation

As first reported last November, anomalies have been noted in the atomic clocks serving Europe’s Galileo satellites. They have occurred on five out of 18 Galileo satellites in orbit, although all satellites continue to operate well and the provision of Galileo Initial Services has not been affected. As ESA Director General Jan Woerner commented during his press briefing on 18 January, no individual Galileo satellite has experienced more than two clock failures, so the robust quadruple redundancy designed into the system means all 18 members of the constellation remain operational. This includes one satellite that supports only the Open Service... (read more)

Positive Signals For Galileo

The in-orbit validation programme for Galileo, Europe's global satellite navigation system, is celebrating three years since the first signal was broadcast by the GIOVE-A satellite. The programme has been gathering momentum since the launch of the GIOVE-A satellite and its success in securing the critical Galileo frequency filing with the International Telecommunications Union (ITU) before the filing expired in June 2006.     Originally designed for a 27 month mission, the satellite has already been operating for more than 3 years. During this period, as well as securing the ITU filing, GIOVE-A has successfully shown that Galileo is technically feasible... (read more)

Galileo Global Navigation System

Maritime aspects of future European satellite navigation
Galileo is Europe’s initiative for a global navigation satellite system, providing an accurate and guaranteed positioning service under civilian control. It will be interoperable with GPS and GLONASS, the two existing military systems, neither of which support safety-critical applications. Galileo will deliver positioning accuracy down to metre range, guarantee availability of service and inform users within seconds of any satellite failure, suiting it for safety-critical applications including maritime navigation. An overview is given of intended Galileo services and performance in this last context. GPS performance after modernisation (2013 and beyond) is considered, as is combined use of Galileo and GPS....

Galileo Network Contracts Signed

As Europe prepares for October's launch of the first Galileo satellites, a worldwide ground network is being put in place. Contracts signed in June 2011 cover satellite control and the systems needed to generate Galileo services.   Europe's satellite navigation system will begin to take shape in space later this year, when the first two Galileo In-Orbit Validation satellites are launched by the first Soyuz flown from French Guiana. Out of six Work Packages for Europe's satnav system to reach full operations, four are already in place. The remaining two were signed during the Paris Air & Space Show at... (read more)

Galileo Interoperable with GPS

ESA’s first two Galileo navigation satellites in space have achieved their latest milestone, transmitting dummy signals in a modulation scheme designed to allow full interoperability with the US GPS once operational services start. An advanced modulation technique offers robust protection against signal interference and the misleading signal reflections known as ‘multipath’. The first two Galileo satellites were launched from Europe’s Spaceport in French Guiana into medium orbits on 21 October 2011, and since then have been progressively put through their paces in a series of tests. These satellites are serving to validate the Galileo system design as well as being... (read more)

Galileo Funding Agreement Reached

At a budgetary conciliation meeting on 23rd November 2007 the European Parliament and Council reached agreement on funding for the Galileo project. It was agreed that Galileo will be funded entirely by the Community. The amount needed by 2013 (a shortfall of €2.4bn) will be found mainly from the revision of the Financial Perspective (€1.6bn of "new" money taken from agricultural expenditure not used in 2007). The rest will come from the redeployment of funds intended for a few programmes that do not come under co-decision (€200 million), the "re-pioritisation" (change in the order of priorities to be funded: €400...

The Outlook for Galileo

Progress and Predictions for European GNSS
Hydro international brings you the recent progress in the much-troubled European satellite navigation system, Galileo. We discuss the motivation behind such a scheme, the problems with funding and the procurement process currently underway. Although costs are spiralling, the anticipated benefits to the economy in terms of revenue, employment and expanding markets are many. Since Galileo is being funded by the EU taxpayer, it is important that projected benefits are realised. Galileo will be Europe's global navigation satellite system (GNSS), which will complement and rival the US Global Positioning System (GPS) and the Russian GLONASS (see ‘Global Navigation Satellite Systems', Hydro...

First Galileo Satellites

The Galileo project is moving towards delivery of a new and advanced global civil positioning service for the benefit of citizens in Europe and the rest of the world. The first two experimental satellites in the Galileo constellation, dubbed GSTB-V2/A and GSTB-V2/B are at an advanced stage towards the In-Orbit Validation phase of the Galileo programme. This ‘first step’ is known as the Galileo System Test Bed (GSTB) and comprises launch of experimental satellites to secure the frequencies allocated to Galileo by the International Telecommunications Union (ITU) to test technologies and the navigation signals specifically developed for this programme. The... (read more)
