Europes satellite navigation system, called Galileo, is planned to become operational in 2008
The European Space Agency warmly welcomes the decision taken today by the European Union Transport Ministers, meeting in Brussels.
Galileo has now been given the official go-ahead but for ESA that simply means that work on Galileo can continue! ESA teams have already been working for a number of years on satellite navigation systems, including the development of critical technologies such as atomic clocks and signal generators.
Developed by ESA in collaboration with the European Union and co-funded by the two organisations on a 50-50 basis, Galileo is a complete civil system, designed to be operational from 2008 and to provide the world in general and Europeans in particular with an accurate, secure and certified satellite positioning system.
Once, we needed to know the time. Now, we need to know the time and also where we are.
So Galileo will be of vital importance to ordinary men and women both in Europe and throughout the world because at present everything depends on the GPS set up and controlled by the US military. Galileo will be in commercial competition with the GPS but will also complement it and provide redundancy. The result will be a continuity of service that could not be achieved by a single system.
The go-ahead for Galileo is particularly important for European industry, which will now be able to develop the advanced technologies required not only for the purposes of the satellite network and its ground support system but also for the numerous applications associated with it.
ESA was able to start work on applications several years ago, thanks to the European Global Navigation Overlay Service EGNOS, which refines current GPS data and foreshadows the services Galileo will provide.
"Galileo marks an important step for Space Europe", said ESA Director General Antonio Rodotá, "because it is the first time a project has been conducted jointly by the European Space Agency and the European Union". It is also the first time the European Union has set up a joint undertaking. The partnership, comprising the European Commission and ESA, will have overall responsibility for the development and validation phase and the preparations for deployment and operations.
It is thus a great step forward for space activities and for Europe, a step that will bring benefits to people all over the world.
The Galileo system will consist of 30 satellites (27 in operation and 3 in reserve), deployed in three circular Medium Earth Orbits at an altitude of 23 616 km and an inclination of 56° to the equator. This will provide excellent coverage of the planet. Two Galileo Control Centres will be set up in Europe to monitor the operation of the satellites and manage the navigation system.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
