Garmin i3 SatNav Review
Posted on 2006-05-30 16:03:20 by LSDsmurfGenerally speaking GPS is accurate to around 10-15 metres in most situations, though a revised system known as WAAS (Wide Area Augmentation System) became available in 2000 which used a combination of special satellites and ground based stations to increase accuracy to between one and two metres. The European equivalent of the US WAAS system is known as EGNOS (European Geostationary Navigation Overlay System)
