That is the general resolution for civilian use. If you can get the military signal then you may get a resolution of 1 meter.my gps device do not give lat/log change untill it cover alomost 20 meters of distance. please help me as soon as possible,
thank you IN ADVANCE
Yes, CKShivaram is right. It is next to impossible.
you cant do anything to improve it... you can say it is used for this purpose and since the resolution is not good enough the demo may not be possible,..............
Differential GPS will get you down to 3m or better, but it's not going to be cheap.
Is there a time requirement for the measurements? If not, you might find this site very interesting.
Supposedly you can get down to 1m with regular GPS, given enough samples.
