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. brgds Aun Johnsen On 05/10/2009, at 11:15, Peter Childs wrote: > I'm sure EGNOS is something else other than the new Euro GPS system, > but I can't for the life of me remember what, something to do with > food and Christmas rings a bell but I can't think what..... > > Anyway so EGNOS is now available for use. > > So what new things can we do with this new available accuracy, and > which devices are EGNOS compatible....
