Check that application features and check it in real situations. You’ll be surprised, I’m sure. m.s.

The problem, is that you cannot do a calibration fo a GPS since it will depend on the satellite constellation which change all day long even if you don’t move. So calibration of a GPS is a no no! If you use accurate GPS measurements, either baseline measurement, of PPP post processing (but you need a GPS slightly more expensive that the regular handheld ;-) ) you can have an accuracy of a few millimetres. So the std-dev should always be given explicitly for GPS.
