Voyager 1 Daily Heliocentric Trajectory Coordinates

Heliocentric trajectory data for the Voyager 1 spacecraft in Heliographic, Heliographic Inertial, and Solar Ecliptic coordinates. The data is produced daily using the 'Mean of Date' method for the Equinox Epoch and originates from NASA's JPL Horizons system. The dataset was last updated on March 13, 2026.

Use Cases

• Modeling spacecraft trajectories relative to the sun based on heliocentric coordinate data.
• Analyzing solar system dynamics using the 'Mean of Date' Equinox Epoch method described.
• Comparing coordinate systems (HG, HGI, SE) for astronomical calculations.
• Using planetary orbit data as a proxy for spacecraft ephemeris, as suggested in the description.

Strengths

• Data originates from NASA's authoritative JPL Horizons system.
• Coordinates are calculated using the defined 'Mean of Date' Equinox Epoch method.
• File formats include BIN, TEXT, and HTML, offering multiple access options.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
