Internet service provides more reliable GPS data
By Isabelle Smets | Thursday 26 July 2012
GPS data can now be obtained not only via satellite signal but also via the internet. Antonio Tajani, commissioner with responsibility for EU satellite programmes, launched, on 26 July, the European Data Access Service (EDAS), a system that makes EGNOS data available. EGNOS, the precursor to Galileo, the future competitor of the American GPS, is the European satellite-based augmentation system. It helps improve the accuracy of GPS satellite signals by correcting errors caused by atmospheric disturbance factors.
With EDAS, GPS data are available via the internet, which gives users the possibility to access EGNOS information even when the satellite signal in space is unavailable, for example due to signal obstruction in urban areas. GPS data can also be used from portable devices. EDAS was tested for several years. “EDAS provides the same information as EGNOS, with the addition of extra data, enabling the creation of new and innovative products and services,” reads a Commission statement. Among such services, it mentions high-precision fertiliser spraying, automatic road tolling, fleet management, inland waterway navigation, dangerous goods transport and accurate area measurement. “The European Commission is fully committed to the service on a long-term basis,” adds the statement.
The EGNOS helpdesk (
egnos-user-support.essp-sas.eu) allows users to register for the service and to consult the EDAS service definition document.
