   Of course.  Sorry if I was vague, but I thought it was obvious in referring
to a stationary posit.  
   Going back and refreshing my knowledge from some DGPS sites, I see this is
was a dumb question and averaging is obviously invalid.  DGPS applies measured
corrections correcting the location error inherent in the basic GPS system. 
Too bad the DGPS data stream is so complex or it would be easier to tap into
the data for an average hacker without one of the DGPS receivers.
   I suspect averaging only minimizes the error to the location which is
defined by the limit of the basic system accuracy.  DGPS would be needed to get
to the" true" location.
