The objective that we had fixed is reached, that is to say the analytical SMART97 solution describes the rotation of the rigid Earth with an accuracy of about 2 as. The good agreement between this analytical solution and the numerical integration of the complete equations entirely warrants the used method and the obtained results.
From SMART97, we are going to take into account the geophysical contributions by convolution with the Earth's transfer functions of Wahr (1981) and of Dehant and Defraigne (1997). It will be also interesting to build an analytical solution of the non-rigid Earth rotation by using the geophysical models in form of analytical expressions.
