Preliminary Global Positioning System results.
Clicking on a station code will take you to a
plot of the north, east and up components
of the station as a function of time.
The station velocities are
in an ITRF2000-NA-fixed reference frame.
The reference frame is described more fully
under the Summary Info button on each station page.
See
gp processing.
for more information about the processing.
Please read disclaimer below.
Disclaimer:
Be advised that these results are preliminary.
The station positions are unchecked
and should not be used for any engineering applications.
There may be errors in the antenna heights.
The velocities are very dependent on the length of the
span of observations.
The presence of outliers (errant observations)
sometimes contaminates the velocities.
Caveat emptor.
