Jack Wrote:You can increase the accuracy of you readings by taking lots of the same point, then averaging them....I once helped a friend plot a readings from a hand-held GPS against time. Very intersting result, from what I remember it varied as a simple sine curve! But that was back in the day when the signal was scrambled.
The one time I left a hand-held GPS sitting on the ground in the middle of a quarry for an afternoon (amazingly no one ran it over!), the points it recorded plotted an elipse 8m long and 5m wide - does that count as accurate? The thing was claiming a 2m or less accuracy throughout! The 'GPS' systems that use phone masts as fixed points seem a far safer bet in Britain, at least in those rare locations where you can actually get a decent phone signal - the only real drawback are the phone bills....

Surely it isn't beyond the realms of possibility for someone to develop an I-phone app that gives you your location/co-ordinates based upon cellular phone land mast triangulation as opposed to sattelites. Seems to me that increase in accuracy would be exponential.....could also combine a WGS/OS co-ordinate transposition programme.

According to Top Gear (Clarkson's usually the most reliable source of info?) there's an app for finding the nearest gay guy in the bar you're in, so locating a b****y great ditch shouldn't be tricky :face-approve:
