Johannes Kepler (1571–1630) answered first the how with his laws of planetary motion in Astronomia nova (1609). Isaac Newton (1643–1727) answered both the how and why with his universal gravitation and laws of motion in . (1687).

A review of the first 20 years of this technique is given by Ryan and Ma (1998). Around the world there are nowadays

The knowledge and therewith the continuous observation of Earth rotation variations is important for various reasons. It is fundamental for the realisation of time systems, the accurate determination of reference frames and pr

Various combined and uncombined methods of GPS algorithms were discussed in detail too to show the advantages of some combining ways. However, again the co
