The orbital elements given below are Keplerian (semi-major axis,
eccentricity, inclination, node angle, arg of periapsis, and mean
anomaly). The reference frame is Earth ecliptic and equinox of J2000.
The central body for each set of elements and the valid time period
for those elements are indicated.
Times are given in both Julian date format in ephemeris time (ET) and calendar date format in Greenwich mean time (GMT). For the general exposure that these elements will receive, GMT has been used and is understood to be the same as universal time (UTC). To clarify any ambiguity between these two time formats, the delta-time (ET minus UTC) and the epoch of each value of delta-time are:
63.184 seconds 01 July 1997
The set of Jupiter-centered elements comprise a complete set of elements
for general use. The body-centered elements at close approach are
included for completeness and are valid only for those times.
The complete set of orbital elements for the Galileo mission are found in four sections: Interplanetary Elements, Probe Elements, Tour Elements, and GEM Elements.
