If you mean how far do you have to travel at a constsnt speed to get an accurate GPS speed, I would like to know that also.

If they are tied together pretty damn accurate. My Lovorsi GPS speedo with a dial and Garmin digital readout are both reading the same but the digital has a slight lag when you accerate quickly.

Did you know ,that it is so you can't use it as a missile control device? GPS was developed for the gov. and civilian units are set up with a delay.

And them Mr. Clinton signed a bill making the government descramble the GPS signal making everything real precise now. Ive seen driver less tractors (GPS driven) that are 14'10" wide go through a 15' gate.
