| Abstract: | Summary A system of reference which is directly related to observations, is proposed for four dimensional studies in Earth space.
The requisite data is used to define both global control network and also polar wandering. The determination of variations
of the Earth’s gravitational field with time also forms part of such a system. Techniques are outlined for the unique definition
of the motion of the geocenter, and the changes in the location of the axis of rotation of an instantaneous Earth model, in
relation to values at some epoch of reference. The instantaneous system referred to is directly related to a fundamental equation
in geodynamics. The reference system defined would provide an unambiguous frame for long period studies in Earth space, provided
the scale of the space were specified.
