Description
Heliocentric trajectory data for the Galileo spacecraft in Heliographic, Heliographic Inertial, and Solar Ecliptic coordinate systems, produced daily. The data originates from NASA's JPL Horizons system and is processed using the 'Mean of Date' method for the Equinox Epoch. The dataset was last updated on March 13, 2026.
Use Cases
Modeling spacecraft orbital dynamics based on heliocentric trajectory data
Analyzing solar wind interactions based on spacecraft position in heliographic coordinates
Calibrating space weather models based on precise solar ecliptic coordinate data
Comparing planetary and spacecraft ephemeris based on the description of using planet orbits as a proxy
Strengths
Data derived from the authoritative JPL Horizons system, a standard source for solar system ephemeris
Coordinates calculated using the defined 'Mean of Date' method for the Equinox Epoch
Includes three specific coordinate systems: Heliographic, Heliographic Inertial, and Solar Ecliptic
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
