Notice about replacement of the reference coordinate system
|
The reference coordinate system used in Japan was replaced from Tokyo-datum to ITRF94,
which was enacted in the law of measurement.
Following it, we are going to replace our reference coordinate system from Tokyo-datum to ITRF94
on March/08/2005.
The positions of stations on our homepage and SEED headers will be changed by the new coordinate system.
The difference of the positions between ITRF94 and Tokyo-datum is about 173-397m.

MT solutions will also be obtained with the new station locations.
But at present we have no plan to re-analyze our past MT solutions and update the source positions.
