Hawkeye Magnetometer Data: Magnetic Field Measurements at 1.9-Second Resolution

Level 0 magnetic field data from the Hawkeye spacecraft magnetometer instrument, provided by NASA. The dataset contains despun measurements at 1.9-second resolution, including scalar and vector magnetic field strength in multiple coordinate systems, spacecraft position, and despin method indicators. A reference paper on the despinning technique is cited, providing methodological context for the data.

Use Cases

• Modeling Earth's magnetosphere based on vector magnetic field data in GSM and SM coordinates.
• Analyzing spacecraft spin dynamics based on the despin method indicator and angular uncertainty estimates.
• Correlating magnetic field strength with spacecraft radial distance from Earth's center for spatial studies.
• Validating magnetic field models using the high-resolution 1.9-second time-series measurements.

Strengths

• Data is provided at a high 1.9-second temporal resolution.
• Includes vector magnetic field data in both Cartesian GSM and SM coordinate systems.
• Contains a documented despin method indicator with six defined states (0-4/5).
• Provenance is clear, originating from NASA's Hawkeye spacecraft instrument.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The license is listed as 'other-license-specified', requiring careful review before use.
