Modern geodetic positioning techniques like VLBI, SLR, and GPS can be used for plate tectonic studies. A very simple model considers a number of rigid plates rotating individually with a constant rotation rate. An equally simple mathematical model, extended to deformable plates, is presented, based on vector calculus, which relates both absolute and relative point positioning observations to the plate rotation and deformation parameters (rotation rate, direction of rotation vector, deformation rate and direction of deformation center) in a consistent and elementary way. The determination of these plate parameters from various geodetic positioning observations is outlined. [ABSTRACT FROM AUTHOR] |
