The effects of selective availability on positioning accuracy
are shown here. A stationary GPS receiver took 6720 measurements at 1-second intervals. While the unit didn't move, the indicated position certainly did. The receiver was located in North London, U.K., at 51 degrees 36.8496' N, 0 degrees 11.149' W. Note that the majority of positions are within 50 meters of the origin.
