EGNOS follows the Tour de France

27.07.2006
The riders in the Tour de France were tracked again this year by EGNOS, the European navigation system that allows precise positioning via satellite. This is the third year that the European Space Agency has been involved in tests of satellite localisation during the Tour de France.
This year, the trials, conducted in partnership with the race organiser - Amaury Sport Organisation (ASO), took place over two of the tour’s stages: the eighteenth – a descent from Morzine, in the Alps, to Macon, in Bourgogne, and then the nineteenth – a time-trial between Le Creusot and Monceau-les-Mines.

During the alpine descent stage, nearly twenty cyclists agreed to wear a receiver in the back of their shirts. The devices, which now weigh only 95 grams, received data from satellites and relayed them for processing by a computer in The Netherlands.

Near the arrival line, in the technical zone of the tour, this data was presented on computer screens, allowing an appreciation of the performance of each tracked rider, notably showing their speed. For the first time it was possible to follow this many riders and see their positions in real time with an accuracy of one metre.

For the individual time-trial between Le Creusot and Montceau-les-Mines, the benefits of satellite tracking were perfectly illustrated by the race situation. Just a day ahead of the final arrival on the Champs Elysées in Paris, three riders were ranked within 30 seconds of one another in the overall standings and the yellow jersey could change wearer at any moment. The immediate visualisation offered by EGNOS showed in real time how the overall standings were being modified as the stage progressed.

A number of riders were equipped with the prototype receivers and in particular the first fifteen in the overall standing were all tracked. This made it possible to have a live view of the positions of the various riders who could hope to take the yellow jersey and therefore to watch American Floyd Landis take the yellow from Spaniard Oscar Pereiro and Germany’s Andreas Kloden grab second place from Carlos Sastre of Spain.

This demonstration was conducted by two Small/Medium Enterprises (SMEs), the Dutch company Sport-Track, which is developing the tracking software, and Trimaran of France, specialising in the production of 3D images. It was possible to see what the Tour de France might be like in the future, since space technologies could be used throughout the race and for all the riders.

These full scale tests showed that satellite positioning can bring an immediate understanding of the race. This has numerous applications, the design of which will depend on the needs of the potential users: the organisers, the teams, the media or the public.

EGNOS (European Geostationary Navigation Overlay Service) is a programme of ESA, the European Commission, and Eurocontrol. It comprises a network of around 40 ground stations distributed throughout Europe to record, adjust and improve data from the American GPS system. The modified signals are then relayed by geostationary satellites to the receivers of system users. In contrast to the 15 to 20 metre accuracy offered by GPS, the European system is accurate to better than 2 metres, and unlike GPS, a military system, the European version provides guaranteed signal quality.

EGNOS, which is currently in pre-operational service, is Europe’s first step in satellite navigation as it prepares for Galileo, which will be the first civilian navigation system, with a constellation of 30 satellites.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
