CDDIS Miscellaneous Documentation for GNSS and Geodetic Data

Miscellaneous documentation, information, and ancillary data from NASA's CDDIS to be used with GNSS, laser ranging, VLBI and DORIS data and analyzed products. The dataset is provided in ISO format and was last updated on 2026-03 13. The organization responsible is the National Aeronautics and Space Administration.

Use Cases

• Interpret GNSS data products based on the ancillary documentation mentioned in the description
• Contextualize laser ranging analysis based on the supporting information provided
• Supplement Very Long Baseline Interferometry (VLBI) studies with the described ancillary data
• Support DORIS data processing based on the available documentation

Strengths

• Provided by the authoritative NASA organization
• Last updated on 2026-03-13, indicating recent maintenance
• Supports multiple precise geodetic measurement systems (GNSS, laser ranging, VLBI, DORIS)

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
