[OSM-talk] EGNOS

[Aun Yngve Johnsen]

EGNOS is just another SBAS (Satellite Based Augmentation System), and  
with EGNOS 100% active we now have tree such systems, including the  
wider known north american WAAS. I hope more such systems can be  
available soon, knowing that India and China also are developing  
similar systems, and there is one active over Japan, which also are  
developing a different system. Such system is very needed in the  
equatorial regions where atmospheric disturbance such as scintillation  
and plasma-bubble effects are more active and can render a handheld  
GPS completely useless at times, but unfortunately most countries  
suffering from these effects don't have the funds for such a project.  
Next milestone in GPS (or I should say GNSS) accuracy will be the  
activation of Galileo, the European equivalent to GPS. A handheld dual  
GPS/Galileo receiver with active SBAS will give you an accuracy you  
never have seen in a small unit, you can almost compete with  
professional units such as those used in land survey and in the oil  
industry.

BTW: GLONASS is also getting more satellites activated, so that is  
almost a reliable alternative to GPS while we wait for Galileo, and  
the chinese plan to activate their COMPASS about same time as Galileo.
