You can increase the accuracy of you readings by taking lots of the same point, then averaging them.
Also having more surveyed in referance points can help you jiggle the position for a better fit, if you got CAD and the digital map data. The more you do this, the more accurate it will be.
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.
