Geomagnetic Experiment on SAC-A contains vector magnetometer and GPS data from the Argentine SAC-A satellite. The magnetometer recorded magnetic field components every 16 seconds, with accompanying positional and limited attitude data from an on-board GPS. The dataset was collected by SCIOPS and last updated in July 1999.
Use Cases
- Analyze time-series patterns in magnetic field components measured every 16 seconds.
- Correlate magnetic field intensity with GPS-provided positional measurements.
- Study the contamination effect on magnetometer readings from the satellite body (no boom).
- Utilize attitude solutions from the GPS for a limited subset of the records.
Strengths
- Magnetic field components measured at a consistent 16-second interval.
- Data includes matching positional measurements from an on-board GPS.
Limitations
- Magnetometer was inside the satellite, so measurements are contaminated by the satellite's own magnetic field.
- Attitude solutions from the GPS are only available for a limited part of the dataset, restricting analysis for much of the data.
