Ancillary Documentation for Geodetic Data Analysis

Miscellaneous documentation and ancillary data supporting the analysis of products from four major space geodetic techniques: GNSS, satellite laser ranging, VLBI, and DORIS. The dataset is provided by the Crustal Dynamics Data Information System (CDDIS) to accompany its primary geodetic data holdings.

Use Cases

• Cross-referencing GNSS data products with official system documentation and calibration reports.
• Validating satellite laser ranging analysis using ancillary station information and instrument logs.
• Interpreting Very Long Baseline Interferometry (VLBI) results with supporting technical memos and session summaries.
• Contextualizing Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) data with system specifications and processing notes.

Strengths

• Covers four foundational space geodetic techniques critical for defining the International Terrestrial Reference Frame.
• Serves as a centralized reference hub for the CDDIS, a primary archive for NASA's Space Geodesy Program.

Limitations

• Specific contents, file formats, and data volumes are unspecified.
• The temporal coverage and update schedule for the ancillary files are unknown.
