Permanent GPS Stations
We apply permanent and campaign GPS/GNSS to precisely monitor crustal motions. For most of the stations, where infrastructure and local regulations authorizes us, stations are in online access. We post-process daily data by GAMIT. Daily results are combined together and with international networks by a Kalman filter. A statistical test at the last step results in estimation of noise that in turn delivers a realistic image of temporally correlated observations and uncertainties.
