Warren,
Understood. I have a couple more questions. Once the thunderbolt has completed
a survey, does it continue to update its position or are the final numbers at
the end of the survey frozen until a new survey has started.
If it continues to update the logging feature in the thunderbolt monitor
outputs the data in a convenient format.I will also give Lady Heather a try.
it has several operational modes such as; stationary, land and a couple of
others. Which mode would be most useful to determine a fixed position.
I have three of the little beasties chugging away and doing an initial survey.
Later on this evening I'll see what they come up with.
Thanks for your help – John

In answer to your original questions,
No problem if you have a good setup including a good sky view, antenna, and
TBolt setup.
It is important to do each run at the different locations at the same time
of the day and average the results for as long as you can.
Best is to do a 24 Hr survey at each location.
see the attached LH plot for the effect of time on location reading error.
Multiple Tbolts on the same antenna don't help, unless they are on different
antennas.
