While consumer GPS navigation devices have been around for a while, the last two or three years have seen sales really take off. Any new mobile phone produced is likely to have GPS capabilities, while the extensive Google Maps applications are now used on smartphones such as the iPhone.
But another advance in GPS technology is the use of true 3D GPS. These new applications display 3D graphics of buildings, monuments and local topography.
There are rumours Google’s Street View applications may become part of a GPS system, allowing realistic views of local areas, but Google has yet to confirm any such plans.
These systems are constantly becoming cheaper and easier to use. Courier businesses and entrepreneurs constantly on the road can use GPS to save the time and effort of relying on often out-dated paper maps.
