How do multiple observation files on the same point that is used repeatedly as a Base Station and which are subsequently processed using DPOS (on the LS) get treated by JField with each successive processing and adjustment application on all collected RTK points?
In theory, one might expect or hope to see some benefit in having multiple Base Station observations contribute to the refinement of the Base Station's location.
To try and discover the answer to this question, first the unadjusted points were exported, then again after the first Base Station file was processed and the adjustment applied, and then lastly, after the second Base Station file was processed and the adjustment applied. The results seemed to indicate that no adjustment was made until the last Base Station file had been processed.
This lead to the question: What happens in DPOS with multiple Base Station Observations?
Tangential question: Which coordinate value should be used for the Base Station on subsequent occupations, or does it matter?
