DORIS Weekly Station Position Product for Geodetic Analysis

Weekly station position solutions derived from the DORIS satellite tracking system. The International DORIS Service (IDS) Analysis Centers compute these solutions by combining Doppler shift or phase measurements from a global network of ground beacons. This dataset is produced and maintained by NASA's Crustal Dynamics Data Information System (CDDIS).

Use Cases

• Analyzing plate tectonic motion rates and directions using weekly station coordinate changes.
• Studying polar motion and Earth rotation variations through time-series of global beacon positions.
• Calibrating and validating other geodetic systems like GPS or SLR with independent satellite-derived measurements.
• Investigating local crustal deformation and fault movement near specific DORIS beacon stations.

Strengths

• Data is produced via a standardized international process, combining solutions from multiple IDS Analysis Centers using least-squares adjustment.
• Provides measurements from a globally distributed network of ground beacons, enabling wide-area geodetic studies.
• Time-series nature with weekly solutions supports analysis of both long-term trends and short-term geophysical events.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source, limiting precise technical assessment.
• Sources conflict on license details, with some specifying 'other-license-specified' and others listing 'None'.
• The exact temporal coverage (start date) of the time series is not stated.
