Hi Bob,

Out of curiosity, why would one turn off SBAS? My first instinct is
that SBAS support could only improve the accuracy of one's fix, as it
supplies additional correction information that improves on the normal
GPS signal. I would (perhaps naively) think that enabling SBAS during
the surveying would improve the results.

Of course, I could very well be mistaken and would be happy to be
corrected by those more knowledgeable.

Cheers!
-Pete
