There is a longer term error of about 7 meters that is more broad scale. WAIS will counteract this one. It has a much slower time fluctuation so it will not affect your distance much The slower you go, the greater ...

If you compare a GPS measurement to a measurement from a measuring wheel, there will be a discrepancy in stat calculations, regardless of GPS chip or post-processing ...

If you take them literally, then you get a much longer distance than you actually moved. If you low pass filter them too much, you cut off corners and get a shorter distance. The usual algorithm is to apply some low pass filtering, but ...

There are two main things that can go wrong with gps accuracy. The first is the quality of the signal, which can be less than for a dedicated gps unit (less space for an antenna and other design compromises). Of course the question of how you carry it comes into play here (a low pocket isn't very good and this may be worse than with a dedicated unit ...
