Comment(by will):

 Thanks to some insight from Marek:

 GPS is known to be inaccurate for several reasons which are
 explained in detail on the web. I collected a few links that should serve
 as
 a starting point:

 Easy to understand summary:
 http://en.wikipedia.org/wiki/Dilution_of_precision_(GPS)

 A rather scientific page with lots of examples:
