Continuously Operation Reference Stations (CORS) networks provide surveying, mapping, and positioning services and play a crucial role in determining crustal displacement. This study processed the continuous Global Navigation Satellite System (GNSS) data collected from 55 CORS stations in the TAST’s CORS in Vietnam to determine the crustal displacement in Vietnam from 2018 to 2021. The processing was performed using online Precise Point Positioning (PPP) services and the displacement model to estimate the velocity of the position time series. The result showed that the horizontal velocity field of all CORS stations is uniform in magnitude and direction, ranging from 25.3 to 42.6 mm/year with accuracy from ±0.1 to ±1.0 mm/year in the south-east direction in the International Terrestrial Reference Frame 2014 (ITRF2014). This study confirms the stability and accuracy of GNSS data from the TAST’s CORS network for crustal displacement analysis.

Las redes basadas en Estaciones de Referencia de Operación Continua (CORS) no solo proveen servicios de posicionamiento, mapeo y sondeo sino que además juegan un rol determinante en la determinación del desplazamiento de la corteza. Para este estudio se procesó la información relacionada con el Sistema Global de Navegación por Satélite (GNSS) recolectada en 55 estaciones CORS de la empresa vietnamita TAST con el fin de determinar el desplazamiento de la corteza en Vietnam entre 2018 y 2021. El procesamiento se realizó con servicios en línea de Posicionamiento por Punto Preciso y se usó el modelo de desplazamiento para estimar la velocidad en la posición de las series temporales. Los resultados muestran que la velocidad horizontal para todas las estaciones CORS es uniforme en magnitud y dirección, con un rango entre 25.3 y 42.6 milímetros por año, con una precisión de ±0.1 a ±1.0 mm/año en la dirección sur-este, según el Marco Internacional de Referencia Terrestre de 2014. Este estudio confirma la estabilidad y precisión de la información GNSS de las redes CORS de la empresa TAST para el análisas del desplazamiento de la corteza.
