CDDIS also provides products derived from these data required for a variety of science observations, including the determination of a global terrestrial reference frame and geodetic studies in plate tectonics, earthquake displacements, volcano monitoring, Earth orientation, and atmospheric angular momentum, among others.
Users can access the data and products available through the CDDIS via anonymous FTP.
