Format:
the coordinates of data are consistent with the ITRF2014 (Altamimi et al., 2016, JGR).
[XYZ files (absolute positions as the Earth-Centred Earth-Fixed (ECEF) coordinates)]
1st line		Date of updating
2nd line		Site name; reference coordinate system
3rd line		Description of each column
after 4th line	Observation start date; absolute positions [XYZ coordinates]; equipment code; vessel code; Observation end date
[ENU files (relative positions from the 1st epoch as local ENU coordinates)]
1st line		Date of updating
2nd line		Site name; reference coordinate system
3rd line		Origin of the plane E-N-U coordinate system (latitude, longitude, ellipsoidal height)
4th line		Position of reference epoch with (E, N, U = 0.0, 0.0, 0.0) from origin point described in 3rd line
after 5th line	Movements from the reference epoch
