The tripod is a survey grade tripod on a limestone terrace (in a horrible location for an antenna).

Heather's precision survey uses the receiver's reported position data.   It does not take advantage of carrier phase/pseduorange/doppler data and post-processing.   Unlike the simple averaging self-surveys that most receivers do it processes the average of medians over 1 minute/1 hour/24 hour intervals.   It typically produces results 1-2m better than the simple self-surveys.   The next thing I want to try is a receiver self-survey vs the post processed results...  I may be able to kludge up a test that does a self-survey / precision survey / post processed survey and compare the results of the methods on the same data set.
