First EGNOS signal in space

After several years of initial definition, detailed design, production 
and deployment activities, the EGNOS (European Geostationary Navigation 
Overlay Service) system started its first signal transmission tests in 
April. This system is Europe's first venture into satellite navigation 
and by early next year will deliver the first European Satellite 
Navigation service. It will augment the two military satellite 
navigation systems now operating, the US GPS and Russian GLONASS, making 
them suitable for many mass market applications such as car navigation, 
bus and truck fleet management, but also for specific applications such 
as assisting blind people when walking in an unknown area. In addition, 
after a certification process, EGNOS will be used for safety-critical 
applications such as flying aircraft or navigating ships through narrow 
channels.

When completed, EGNOS will consist of three geostationary satellites and 
a network of ground stations that will transmit signals containing 
information on the reliability and accuracy of the positioning signals 
sent out by GPS and GLONASS. It will enable users in Europe and beyond 
to determine their position within 2m compared with about 20m with GPS. 
Since 2000 a prototype of the system (the EGNOS System Test Bed, ESTB) 
has been providing test signals, fully demonstrating its worth and validity.
 
By spring 2004 the full network needed for this augmentation system will 
have been deployed all around Europe and beyond. It will comprise 
monitoring stations, called RIMSs (Ranging and Integrity Monitoring 
Stations), and several Master Control Centres, the first of which is 
already installed in Langen, Germany.

Altogether, nearly 40 stations will be deployed.

This installation phase includes the testing of all equipment. This 
necessitates the availability of a signal in space and that is why the 
first signal is so important.

EGNOS is a joint project of the European Space Agency, the European 
Commission and Eurocontrol, the European Organisation for the Safety of 
Air Navigation. It is Europe's contribution to the first stage of the 
global navigation satellite system (GNSS) and is a precursor to Galileo, 
the full global satellite navigation system under development in Europe.

Event in Langen, Germany:

This  "first signal in space" of the satellite system will be relayed 
from the first EGNOS master control centre in Europe, located in the DFS 
air straffic control centre in Langen, near Frankfurt (Germany).

The European Space Agency and DFS are pleased to invite you to this 
event, which takes place on 6 June at 10:30 hrs at the headquarters of 
DFS Deutsche Flugsicherung GmbH, Am DFS-Campus 10, 63225 Langen (Germany).

Dieter Kaden, DFS Chairman and Chief Executive Officer, and Claudio 
Mastracci, ESA Director of Application Programmes, will be there to 
describe the various functionalities of the system.

We would appreciate it if you would reply by fax as soon as possible to 
DFS using the attached form or contact us by telephone on +49 6103 
707-4111 or by e-mail to claudia.sielaff@dfs.de . [NOTE: Not attached -
