SAC-C Mag-R: Calibrated Magnetic Field and Coordinate Rotation Data

1-second magnetic field vector measurements from the SAC-C spacecraft's Compact Spherical Coil Fluxgate Magnetometer. The dataset includes matrices describing rotations between the J2000 reference system, stellar compass coordinates, and Earth Centered Earth Fixed polar coordinates. It is provided by the National Aeronautics and Space Administration.

Use Cases

• Calibrate spacecraft magnetometer readings based on the 1-second measurement cadence.
• Transform magnetic field vectors between coordinate systems using the provided rotation matrices.
• Analyze magnetic field variations in Earth's orbit using the calibrated CSC data.
• Validate spacecraft attitude and orientation models against stellar compass coordinate data.

Strengths

• Data includes calibrated measurements from a fluxgate vector magnetometer.
• Provides high-resolution 1-second time-series data.
• Includes matrices for precise coordinate system transformations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
