ANGULAR VELOCITY OF TECTONIC PLATES DETERMINED BY NON-RIGOROUS COMBINATION OF SPACE GEODETIC TECHNIQUES

The orientation of the Earth is defined by Earth orientation parameters that are measured by space geodetic techniques. The results provided by these techniques differ from each other. The method presented here combines these results in order to get a representative solution of the Earth orientation parameters. Other products of the method are improved coordinates and velocities of collocations stations distributed on six major and two minor tectonic plates. The fact that the stations lie on their plates gives us possibility to describe movements of these plates during our data interval. All new results are compared with the ones published by ITRF 2005 and presented hereafter.
