The velocities would need to be non-linear.
The question comes down to this. Is the displacement caused by ground displacement or something mechanical? If it's mechanical, then an updated coordi...
If the daily variations were reliably understood, guaranteed to be caused by surface motion and not a change in the antenna or some other non-geologic...

What amazes me is how inexpensive outfitting a survey office can be now compared to a couple of decades ago. I used to "play-like" with the Allen Prec...
At the very least exclude stations that vary more than some tolerance from OPUS solutions automatically, and perhaps add a flag somewhere that the las...
