Rob —
I am curious about something. My Trimble Scout has a "user range accuracy"
display. I think this is obtained from the data message received from the
satellites. All but 4 or 5 have a URA of 32 meters but the rest have a URA of
either 2 or 4 m. I have assumed that the 2 or 4 m URA's are from satellites
with S/A off. Is that correct?
