High-Rate Beidou Satellite Ephemeris Data from Global Ground Stations

Global ground-based GNSS stations collect high-rate Beidou broadcast ephemeris data, formatted as sub-hourly RINEX files. NASA's Crustal Dynamics Data Information System (CDDIS) archives and distributes this data, which includes signals from multiple global navigation systems. The dataset is actively maintained, with a last recorded update in March 2026.

Use Cases

• Precise orbit determination for the Beidou satellite constellation using broadcast ephemeris parameters.
• Analysis of signal integrity and satellite clock performance for the Beidou navigation system.
• Development and validation of multi-GNSS positioning algorithms that incorporate Beidou data.
• Scientific studies in crustal dynamics and plate tectonics using high-rate positional data from a global receiver network.

Strengths

• Data originates from a global permanent network of ground-based receivers, ensuring wide spatial coverage.
• Provides high-rate (1-second) Beidou broadcast navigation data in standardized RINEX format.
• The CDDIS archive includes data from multiple GNSS systems (GPS, GLONASS, Galileo, Beidou, QZSS, IRNSS, SBAS) since 2011, allowing for comparative analysis.

Limitations

• Specific row counts, file sizes, and detailed column schemas are not provided by any source platform.
• Sources conflict on license details, with one specifying 'other-license-specified' and another listing 'None'.
