Resumen
Se analiza las soluciones semanales de EUREF EPN (EUREF Permanent Network) en formato estándar SINEX (Solution Independent EXchange format) desde principios de 1996 hasta principios de 2021 determinando las posiciones y velocidades de las estaciones de dicha red, en el marco de referencia IGb14. Se partió de coordenadas y velocidades a priori y discontinuidades de las estaciones EPN resultantes de alinear EPN a IGS14, se utilizó Bernese v 5.2 para el procesamiento , obteniendo valores de las traslaciones de -1.05 +/- 0.06 mm, -1.55 +/- 0.06 mm y de -1.51 +/- 0.06 mm para las componentes X, Y y Z respectivamente, las diferencias entre las coordenadas calculadas y las publicadas (EPN C 2145), son de - 0.11 +/- 1.08 mm, -1.24 +/- 1.57 mm y -1.86 +/- 3.02 mm para las componentes N, E y U (altura), respectivamente, y las diferencias medias de las velocidades para las estaciones de referencia son de 0.31 +/- 0.22 mm/a, 0.00 +/- 0.11 mm/a, 0.27 +/- 0.25mm/a para las componentes X,Y,Z respectivamente.
The weekly solutions of EUREF EPN (EUREF Permanent Network) in standard SINEX format (Solution Independent EXchange format) are analyzed from the beginning of 1996 to the beginning of 2021, determining the positions and speeds of the stations of said network, in the framework of reference IGb14. It was based on a priori coordinates and velocities and discontinuities of the EPN stations resulting from aligning EPN to IGS14, Bernese v 5.2 was used for the processing, obtaining translation values f -1.05 +/-0.06 mm, -1.55 +/- 0.06 mm and -1.51 +/- 0.06 mm for the X, Y and Z components respectively, the differences between the calculated coordinates and those published (EPN C 2145) are -0.11 +/- 1.08 mm, - 1.24 +/- 1.57 mm and -1.86 +/- 3.02 mm for the N, E and U (height) components, respectively, and the mean differences of the velocities for the reference stations are 0.31 +/- 0.22 mm / a, 0.00 +/- 0.11mm /a, 0.27 +/- 0.25mm / a for the X, Y, Z components respectively.
