Distance with GPS impossible? <1% accuracy

I read almost anything that catches my eye with an interesting looking title. Except unix related PC questions, out of my depth there...

I know I m going to regret jumping in here, but I have been experimenting with GPS accuracy for another form or racing, although it is MUCH slower than motorcycle racing. Yes, the error is like 6 to 12 feet. But when you are in a small area, the error seems to remain relatively consistent over a short period of time.

So if position A is measured and that measurement is off by x feet on a heading of n, that error remains consistent for a while. In my case, I need to do this for 5 to 10 minutes and 10 feet error, while not desirable, is acceptable.

Just my 2 cents.

I agree! Cool product, but I don't see the price. I'm sure it is more accurate than 1%, see it is possible! To all you pessimists. Especially with the odometer input, that makes it perfect for measuring distance.
