| Abstract: | Japanese old geodetic datum TD1918 has been used since the beginning of 19 Century, and now it can not serve well for the progress of economic, social and military development. Hence a new geocentric 3D geodetic datum JGD2000 has been utilized since 2002. The geodetic system and its corresponding coordinate frame for JGD2000 are introduced. The coordinate transformation between the two systems, old one and new one, are given in numerically. |
