P12 V Radio Science: Line-of-Sight Gravity Data from 351 Pioneer Venus Orbits

351 orbits of the Pioneer Venus Orbiter were tracked to produce line-of-sight gravity data. The dataset is a table containing spacecraft latitude, longitude, accelerations, and altitude, with accelerations derived from raw Doppler residuals and expressed in mm/s**2. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Modeling Venus's gravity anomalies based on line-of-sight acceleration data
• Analyzing the relationship between surface topography and gravity based on latitude, longitude, and altitude columns
• Calibrating or validating gravity models for Venus based on spacecraft-derived measurements

Strengths

• Data derived from 351 distinct spacecraft orbits, providing multiple observations.
• Acceleration data is provided with a specific conversion factor (multiply by 100) to obtain gravity in milligals.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
