URAP/RAR: Ulysses Spacecraft Radio Astronomy Receiver 144-Second Averaged Data

144-second averages of electric field intensities from the Ulysses spacecraft's Unified Radio and Plasma Wave Instrument Radio Astronomy Receiver (URAP/RAR). The data includes 76 frequency channels from 1.25 kHz to 940 kHz, with polarization and summation modes recorded. National Aeronautics and Space Administration (NASA) provides this data for the Ulysses mission.

Use Cases

• Analyzing solar radio burst patterns based on electric field intensities across 76 frequency channels.
• Studying polarization mode changes in radio wave data based on LO_POL_MODE and HI_POL_MODE variables.
• Investigating telemetry bit rate effects on signal averaging based on IBPS values.
• Identifying Jovian Kilometric Radiation signatures based on high-frequency channel data.
• Correlating electric field dynamics with spacecraft operational modes based on summation and polarization flags.

Strengths

• Data includes 76 distinct frequency channels from 1.25 kHz to 940 kHz.
• Each record contains detailed metadata including date, time, polarization mode, summation mode, and telemetry bit rate.
• The averaging period of 144 seconds corresponds to the instrument's basic cycling time.

Limitations

• Column-level documentation is absent; field semantics must be inferred from the Fortran read statement.
• Row count is unknown, which may limit suitability assessment.
• Data format is BIN, requiring specialized tools for access and conversion.
