EGNOS Test Bed joins forces with the Mediterranean Test Bed

ARCHIVOVANÝ OBSAH 01 ÚNO. 2001 1306

The availability of the EGNOS test signal was extended last month when Inmarsat's Indian Ocean Region (IOR) satellite began broadcasting it over a large area including Eastern Europe, the Middle East, Russia, central Asia and India. Inmarsat's Atlantic Ocean Region East (AOR-East) satellite has been broadcasting the signal over a wide area of Western Europe for the past year. As well as extending signal coverage, the new availability allows users to receive signals from two different directions providing line-of-sight diversity and extra redundancy.

Broadcasting from the IOR has been possible thanks to the interconnection with the Mediterranean Test Bed (MTB), which has been developed jointly by ENAV, the Italian air traffic service provider, and Telespazio. This test bed consists of monitoring stations, which collect integrity data on US global positioning satellites (GPS), and a station in Fucino, Italy which transmits a signal modulated with the integrity data to the IOR satellite. When additional monitoring stations come on line, signal availability will be further extended.

The EGNOS System Test Bed (ESTB) provides a unique opportunity for validating new application developments in a realistic environment, in preparation not only for EGNOS operation, due from 2003, but also for future GALILEO services. The ESTB can be used by any company or organisation with an interest in testing or promoting EGNOS and navigation applications in general.

Road test for EGNOS, Europe’s new satellite navigation system

A Fiat car is putting a European satellite navigation system through its paces in Turin, Italy this week. EGNOS, which is being developed by a collaboration led by the European Space Agency, will be monitoring the car’s position on a map with an accuracy of close to one metre.

What is EGNOS?

The European Geostationary Navigation Overlay Service (EGNOS) is Europe’s Satellite-based Augmentation System (SBAS). It augments the signals from Global Navigation Satellite Systems (GNSS) to improve their accuracy, integrity and continuity so that they can be used for Safety of Life applications—operations where a malfunction of the system would lead to a major human or environmental catastrophe. EGNOS is used throughout Europe to help guide aeroplane landings in over 500 airports and helipads across 35 countries.

How does EGNOS work?

EGNOS provides the information needed to use navigation signals from GPS satellites for safety critical applications. It improves the accuracy of position measurements from a few metres to around one metre, informs users of the errors in the position measurements and warns of disruption to a satellite signal within six seconds.
