ELFIN A CubeSat Ephemeris: Position, Velocity, and Spin Data at 1-Second Resolution

The Electron Losses and Fields Investigation (ELFIN) Mission is a Space Weather Mission using three Scientific Instruments in a 3U+ CubeSat. This Level 1 data product contains probe state information, including CubeSat position, velocity, spin attitude, spin rate, and spin phase, recorded at a 1-second cadence. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling satellite orbital trajectories based on position and velocity data.
• Analyzing spacecraft spin dynamics and stability based on spin rate and phase data.
• Calibrating scientific instrument readings based on precise satellite attitude information.
• Studying space weather phenomena by correlating satellite state with particle and wave measurements.

Strengths

• Data is provided at a high temporal resolution of 1 second.
• Produced by the authoritative source, the National Aeronautics and Space Administration.
• Last updated in March 2026, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in a BIN format, which may require specialized tools for access.
