The European Space Agency announced plans to upgrade the European Geostationary Surface and Geostationary Service (EGNOS), significantly increasing GPS accuracy.
EGNOS consists of three geostationary satellites and a 40 terrestrial network to verify GPS signals. EGNOS improves the accuracy and reliability of signals from the global navigation satellite systems, increasing safety in a number of cases, such as aircraft flight, navigation of narrow-channel ships,
The upgraded system will offer even more reliable results as the the accuracy of the position is now increased to three meters. EGNOS signals also guarantee the integrity of the data they offer and warn when the output is not considered valid or can not be accurately calculated.
Improved position accuracy will benefit primarily the aviation industry, as verifiable and accurate location data is very important for security reasons. Higher-precision position data can be used in aircraft flight so that pilots know they will not collide in a mountain or the sea when there is low visibility, adverse conditions, or fly over difficult terrain.
The improved system is also expected to have multiple benefits for a set of applications that handle geospatial data and will also facilitate rescue teams to locate people at risk.
The European Space Agency has already signed contracts to upgrade EGNOS to V2.4.2I and V2.4.2 and its plans include the incorporation of its own constellation of Galileo satellite satellites into EGNOS, considering that two fleet of navigation satellites are better than one.
Many are also commercially available GPS devices that include EGNOS, with the list listing more than 100 devices from various companies, such as Garmin, Wintec and Magellan.
