Voyager 2 PRA: Neptune Encounter Low-Frequency Radio Data, 1989

May 25 to September 27, 1989 data from the Voyager 2 Planetary Radio Astronomy instrument during its Neptune encounter. The dataset contains high-rate frames, each 48 seconds long, with a 28-octet header and 1,280,000 octets of data per file. It was produced by the National Aeronautics and Space Administration.

Use Cases

• Analyzing temporal patterns of Neptune's radio emissions based on the high-rate time-series data.
• Studying the spectral characteristics of planetary phenomena using the four frequency channels described in the header.
• Correlating radio flux measurements with other Voyager 2 instrument data based on the precise spacecraft time stamps.
• Investigating signal processing and data acquisition methods for deep-space radio instruments based on the described frame and line structure.

Strengths

• Data covers a defined four-month encounter period from 1989-05-25 to 1989-09 27.
• Each data file has a detailed 28-octet header specifying year, day, time, spacecraft, frequency channels, and bandwidth.
• The data structure is explicitly documented, including the 48-second frame duration and 800-line logical division.

Limitations

• Column-level documentation is absent; field semantics for the main data stream must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
