EGNOS satellite navigation system delivered to ESA by industry

21.06.2005


A key step for satellite navigation in Europe was achieved on 16 June 2005, with the formal completion of the technical qualification of the European Geostationary Navigation Overlay Service (EGNOS) and the acceptance of the EGNOS system delivered to ESA.



This formal review, called the Operational Readiness Review (ORR), marked the completion of more than 8 years of intensive work by ESA and European industry. The ORR involved the acceptance of the EGNOS system delivered to ESA by an industrial consortium lead by Alcatel Space with more than forty European companies.

EGNOS is a joint project of the European Space Agency (ESA), the European Commission (EC) and Eurocontrol - the European Organisation for the Safety of Air Navigation. ESA is in charge of the system development and technical qualification. EGNOS is Europe’s contribution to the first stage of the global navigation satellite system (GNSS), paving the way for Galileo, the first civil complete satellite navigation system.


Three special EGNOS satellites located in geostationary orbit above Europe transmit a GPS-like signal that improves the GPS accuracy down to 1 to 2 metres. Service guarantee and integrity information is also provided. EGNOS measured performances are beyond initial expectations, another demonstration of the excellence of the European engineers and technology.

More than 60 international experts from ESA gathered in Toulouse during May 2005. Eurocontrol, the Galileo Joint Undertaking and the EGNOS Operator and Infrastructure Group took part in this comprehensive review.

Experts assessed whether the EGNOS system could be accepted as ready for operation. The focus was on several aspects such as the functional qualification of the system and its operability, the stability of the system in its real environment, the system performance and compliance with the requirements and Safety and Product assurance issues including the qualification of the software and the completeness of the deliverables.

This review concluded earlier work carried out in the previous project phases, such as the System Preliminary Design Review in November 1998, a Critical Design Review in January 2002 followed by the EGNOS Factory Qualification Review in January 2004.

Today, the deployment of EGNOS is nearly complete, with around 30 Ranging and Integrity Monitoring Stations (RIMS) deployed in 21 countries; 4 Mission Control Centres (MCCs) deployed in Spain, Italy, UK and Germany; 6 Navigation Land Earth Stations (NLESs) deployed in Italy, France, Spain and the UK and some support facilities in Spain and France.

Following this review, EGNOS initial operations can start through a contract with the European Satellite Service Provider (ESSP). By early 2006, when operational stability is expected to be reached, the EGNOS open service will be declared formally available to the general public over Europe for non safety-of-life applications, free of direct charges. Today, the general public can already receive the EGNOS signal on a test basis.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
