Abstract:We use Hector software to calculate the observation data of 10 continuous stations of CMONOC of Shanxi province from 2010-11 to 2021-01. We obtain the coordinate time series of the continuous stations, and determine the optimal noise model and the corrected velocity field. The results show that: white noise (WN), flicker noise (FN) and power-law noise (PL) mainly exist in the Shanxi coordinate time series data; the optimal noise model in the North direction is WN+PL; the optimal noise model in the east and up directions are WN+FN. Taking into account the influence of colored noise, the average moving speed in the horizontal direction of CMONOC in Shanxi based on the ITRF2014 framework is 33.542 mm/a, and the moving direction is SEE 26°22′12″. The average movement speed in the vertical direction is 2.214 mm/a, showing an uplift trend.
