Attempt to obtain the general relativistic planet's motion by special relativity techniques
Yoshio Kubo
It is attempted to derive the general relativistic (GR) equation of motion for planet and its solution solely by the special relativity (SR) techniques. The motion of a planet rela…

The Earth's figure axis determined from the polar motion data
Yoshio Kubo
The polar motion data is analyzed to obtain accurate position of the figure axis referred to the Earth-fixed frame. The variation of the figure axis should be the basic object to w…
