Global Navigation Satellite System Ground Receiver Data from NASA CDDIS

NASA's Crustal Dynamics Data Information System (CDDIS) archives supporting information for ground-based Global Navigation Satellite System data. The archive primarily holds data from the U.S. GPS and Russian GLONASS systems, with data from other global systems like Galileo and Beidou added since 2011. This collection supports autonomous geo-spatial positioning with global coverage.

Use Cases

• Analyzing signal structure and orbit data from multiple GNSS constellations (GPS, GLONASS, Galileo, Beidou) for system interoperability studies.
• Processing time-series of ground receiver data to model tectonic plate movements and crustal deformation.
• Using Satellite Based Augmentation Systems (SBAS) data to improve positioning accuracy for regional applications.
• Comparing data holdings and product formats from different GNSS providers archived since 2011.

Strengths

• Includes data from multiple global satellite navigation systems (GPS, GLONASS, Galileo, Beidou, QZSS, IRNSS, SBAS).
• Provides global coverage for geo-spatial positioning applications.
• Archived by NASA's authoritative Crustal Dynamics Data Information System (CDDIS).

Limitations

• Specific data volume (row count), file formats, and column structure are not provided in the description.
• The recency and update frequency of the archive are unknown.
• License terms for data use and redistribution are unspecified.
