ARTEMIS-P1 Ephemeris: Daily Heliocentric Trajectory Coordinates

Heliocentric trajectory data for the ARTEMIS-P1 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

• Model spacecraft heliocentric trajectories based on coordinate data.
• Analyze solar system dynamics based on heliographic coordinate transformations.
• Compare spacecraft ephemeris with planetary orbital data as a proxy.
• Study the drift of the First Point of Aries based on the Equinox Epoch calculation methods described.

Strengths

• Data originates from NASA's JPL Horizons system, a recognized authority.
• Coordinates are calculated using the 'Mean of Date' Equinox Epoch method, a common standard.
• 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.
