GLONASS Satellite Orbits with Real-Time Position and Velocity

Ground-Based GNSS-based Upper Atmospheric Realtime Disaster Information and Alert Network (GUARDIAN) GLONASS daily accumulated real-time Precise Orbit Determination (POD) orbits (60-second sampling, 24-hour files) from NASA CDDIS. This dataset provides a time series of position and velocity components, along with formal 1-sigma uncertainties, for healthy satellites in the GLONASS constellation, generated at JPL's Global Differential GPS Operations Centers. Daily files can be concatenated to extend temporal coverage.

Use Cases

• Precise orbit determination and validation by analyzing the minute-by-minute position and velocity components.
• Satellite constellation health monitoring by tracking only healthy GLONASS satellites.
• Geodetic reference frame studies using the high-temporal-resolution orbital data.
• Real-time disaster information and alert network applications, as indicated by the GUARDIAN project context.
• Error analysis and uncertainty quantification using the provided 1-sigma uncertainty values for positions and velocities.

Strengths

• Provides high-temporal-resolution data with a 60-second sampling rate for detailed orbital analysis.
• Includes formal 1-sigma uncertainty estimates for both position and velocity components, enabling error assessment.
• Generated in real-time by JPL's Global Differential GPS Operations Centers, indicating operational reliability.
• Data is structured for concatenation with other daily products to create longer time series.

Limitations

• Critical metadata such as column names, row count, and dataset size are unknown across all sources.
• Sources disagree on license information, with some specifying 'other-license-specified' and others listing 'None'.
• The dataset is limited to healthy GLONASS satellites, excluding data from unhealthy or decommissioned satellites.
