Hi Pete, >From Bob Camp's comments, I think you're right. I hadn't considered survey as >an issue by itself. I've only been concerned about timing, and one of the >Ublox manuals says to turn off SBAS for timing applications.

Also, turn off SBAS, set your max and min number of sats (defaults are probably what you want), and the satellite elevation mask. The elevation mask defaults to 5, but can you really see that low? 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.
