Voyager 2 Uranus PRA Low-Frequency Receiver Band, 60 ms High Rate Data

Voyager 2 Planetary Radio Astronomy (PRA) instrument data captured during the Uranus encounter from 1985-10-24 to 1988-07 14. Each file represents a 48-second high-rate frame containing 1280000 octets of data, with a 28-octet header detailing time, spacecraft, and frequency information. The data were collected by NASA and consist of 16-bit numbers representing flux measurements at two frequencies sampled every 138.88 µs.

Use Cases

• Analyzing temporal patterns of Uranus's radio emissions based on the multi-year encounter period described.
• Studying signal flux at specific low-frequency channels based on the header's frequency and bandwidth fields.
• Reconstructing the spacecraft's observational timeline based on the detailed time and FDS count header data.
• Developing or testing signal processing algorithms for high-rate, dual-frequency sequential sampling data as described.

Strengths

• Covers an extended Uranus encounter phase from 1985-10-24 to 1988-07-14.
• Provides high temporal resolution data with samples acquired every 138.88 µs.
• Includes a structured 28-octet header with year, day, hour, minute, second, spacecraft ID, FDS count, and four frequency values.

Limitations

• Column-level documentation is absent; field semantics for the 1280000 octets of data must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment for large-scale processing.
• Data format specifics for the 16-bit number stream and logical line structure require careful interpretation.
