Currently a fixed bias vector model between the IGS and IVS points (IGS - IVS bias vector: [92.371, 4.965, 49.127] [m]) is assumed for the position model, but there may be a relative-position change between the two points. The model will be updated regularly by the results of post-seismic geodetic VLBI campaign. One-sigma position accuracy of each component seems to be about 3 to 5cm after the earthquake.

The Usuda 64m station has a DSN station id of DSS-48. Altitude of the weather station at Usuda is about 34 meter lower than that of the reference point of the Usuda 64m station. The barometric pressure shall be calibrated by the user of the weather data from Usuda.

Station positions and velocities of the Uchinoura 34m station

The coordinate of the Uchinoura 34m station has not been affected by the earthquake.
