GLONASS Satellite Attitude Quaternions from Real-Time Ground Network

NASA's GUARDIAN network provides daily 24-hour files of attitude quaternion components for healthy GLONASS satellites, sampled every 30 seconds. The data is generated in real-time by JPL's Global Differential GPS Operations Centers and can be concatenated across days for longer time series analysis. This dataset supports precise orbit determination and monitoring of satellite orientation.

Use Cases

• Precise Orbit Determination (POD) by integrating quaternion data with orbital models.
• Satellite attitude and health monitoring using time-series quaternion components.
• Analysis of rotational motion and orientation stability for GNSS constellations.
• Concatenating daily files to study long-term trends in satellite pointing.

Strengths

• Provides real-time data generation from JPL's Global Differential GPS Operations Centers.
• Offers high temporal resolution with attitude quaternions accumulated every minute (30-second sampling).
• Covers the entire GLONASS constellation, focusing on healthy satellites.

Limitations

• Specific column names, row counts, and total dataset size are not provided by any source.
• The license is ambiguously listed as 'other-license-specified' without detailed terms.
• Data format details are limited to BIN, ISO, and HTML file types.
