EGNOS ‘Open Service’ available: a new era for European navigation begins today

1 October 2009

During a press conference today, Mr Antonio Tajani, European Commission Vice-President for Transport Policy, announced the official start of operations for EGNOS, the European Geostationary Navigation Overlay Service. The EGNOS ‘Open Service’ is now available.

This is a major milestone for the project: its primary service is now available to all users equipped with EGNOS-compatible receivers. Most mass-market satellite navigation receivers being sold today are ready for EGNOS.

EGNOS is a satellite-based augmentation system that improves the accuracy of satellite navigation signals over Europe. The system consists of transponders aboard three geostationary satellites over the eastern Atlantic Ocean and Europe, linked to a network of about 40 ground stations and four control centres.

The EGNOS ground stations receive signals sent out by the US GPS satellites. Information on the accuracy and reliability of these signals is relayed to users via the geostationary satellite transponders. This allows them to determine their position to within two metres, compared with about 20 metres for GPS alone. The Open Service is provided free of charge.


EGNOS is the first pan-European navigation satellite system. It was developed as a joint project by ESA, the European Commission (EC) and Eurocontrol, the European Organisation for the Safety of Air Navigation.

ESA had overall responsibility for the design and development of the EGNOS system and placed a contract with a consortium led Thales Alenia Space, France, to develop the system. After completing development, the EGNOS system was handed over to the EC on 1 April.

EC now owns and manages the EGNOS system. ESA is the design and procurement agent through a delegation agreement with the EC.

The European Satellite Services Provider, ESSP SaS, founded by seven air navigation services providers and based in Toulouse, France, manages EGNOS operations. A contract between the EC and ESSP SaS was signed on 30 September. The contract provides for the management of EGNOS operations and the maintenance of the system until the end of 2013.

Já alguém daqui experimentou se os vossos Receivers captam os satelites do Egnos?

Vou ter de ver se o meu capta.

Eu tenho um Holux GPSlim 236, e por uam rapida pesqusia que fiz, parece que funciona. Aliás qualquer gps que suporte waas, também suporta o egnos.

Agora pode vir é desactivado lol

Tenho de ver com o GPSviewer se ele me está a conectar a isso.

Mas se apanhar Satélites com números na casa dos 100 e pouco. São esses.

E ja pude confirmar no site da Holux:


‧ Use SiRF Star III chipset.

‧ 20 - channel GPS Receiver for fast acquisition and reacquisition

‧ 200,000 effective correlators for fast Time To First Fix (TTFF), even at poor satellite signal.

Built-in WAAS/EGNOS Demodulator.

‧ Built-in rechargeable/ changeable Lithium-ion battery for at least 10 hours operation.

Built-in rechargeable battery for memory for RTC backup and fast Time To First Fix (TTFF)

Support NMEA0183 v2.2 data protocol or SiRF binary code

FLASH based program memory. New software revisions upgradeable through serial interface

Provide expand terminal and can contact to other system without Bluetooth device
