Hello Tom,
on the measurements did you use Auto Survey on these receivers? Or did you
give them a surveyed antenna position?
Even good GPS's I have seen have a 3-5 feet height error or so from Auto
Survey.
I wonder how much better these units would perform if they get a well
surveyed position set manually?
Maybe their performance is so good already that it wouldn't make a
difference in ADEV.
bye,
Said
