Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) Geocenter Time Series Product from the NASA Crustal Dynamics Data Information System (CDDIS). DORIS observations from a global network can be utilized for a variety of products. Analysis Centers (ACs) of the International DORIS Service (IDS) retrieve DORIS data on a regular basis to compute various DORIS products from data generated by the DORIS beacons supporting the IDS network, including the time series of coordinates of the geocenter or the origin of the terrestrial reference frame. The IDS Analysis Center Coordinator combines these solutions to produce an official IDS geocenter product. The geocenter time series are available in text format.
