Voyager 1 RSS: Titan Atmosphere Radio Occultation Raw Data, 1980

November 1980 raw voltage data sampled at 300,000 samples per second from the Voyager 1 Radio Science Subsystem during its Titan occultation. The dataset was produced by NASA and includes signals from S-band and X-band receivers used to derive atmospheric profiles. It contains the raw outputs plus ancillary files for analysis.

Use Cases

• Deriving atmospheric temperature and pressure profiles as a function of height based on signal frequency/phase data.
• Detecting and analyzing Titan's ionosphere from the dual-frequency microwave radio signals.
• Studying signal refraction and bending in a poorly characterized atmosphere using the fixed antenna offset data.
• Calibrating or validating radio occultation models for outer planetary moons using the raw voltage samples.

Strengths

• Data sampled at a high rate of 300,000 samples per second for both S-band and X-band receivers.
• Includes profiles derived for both the ingress and egress sides of Titan's atmosphere.
• Provides coherent, dual-frequency signals from a precision onboard Ultra-Stable Oscillator.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Absolute voltage levels are not calibrated, as noted in the description.
