High-Rate GNSS Techniques for the Detection of Large Seismic Displacements
Other conference contribution, 2009
Detection of the seismic strong motion is of great importance
for earthquake studies. We have investigated the usage
of high-rate sampled Global Navigation Satellite System
(GNSS) data to measure seismic motion by implementing
an industrial robot simulating the displacements close to an
earthquake. The motion of the robot is tracked by Global
Positioning System (GPS) signals. Two baselines-400 m and
60 km-from the robot to reference stations are used to process
the observed GPS data. Both methods give similar (within
0.5 mm) Root Mean Square (RMS) differences between the
estimated and the commanded coordinates. The RMS differences
are approximately 3.5 mm in the east component, 5 mm
in the north component, and 7 mm in the vertical component.
