CDDIS: Ancillary Documentation for Space Geodesy Data Products

Miscellaneous documentation and ancillary data from NASA's Crustal Dynamics Data Information System (CDDIS) to be used with space geodesy data products. The documentation supports data from Global Navigation Satellite Systems (GNSS), laser ranging, Very Long Baseline Interferometry (VLBI), and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS). The dataset was last updated on March 13, 2026.

Use Cases

• Interpret GNSS data products based on the available ancillary documentation.
• Contextualize laser ranging measurements based on the supporting information.
• Supplement VLBI analysis based on the provided documentation.
• Understand DORIS data formats and processing based on the ancillary files.

Strengths

• Produced by NASA, an authoritative source for space science data.
• Last updated on March 13, 2026, indicating recent maintenance.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
