> And the methods are?
The topic is a little bit wrong formulated. It should be "estimation of
resulting satellite inaccuracy".
It's not very complicated: Assuming that a fixed mounted GPS antenna =
should
lead to totally stable readings one has only to record all and plot e.g. =
LON
vs. LAT and the resulting cloud of dots shouldn't occupy an area of more
than 2x2 meters. I did that with an ordinary GPS w/o differential unit =
in my
garden just after begin of yugoslavian war and was surprised about the
result. I recorded 2h an got only 3 readings with a 1m difference in =
either
direction.=20
