This directory contains Galileo spacecraft trajectory data in various         
coordinate systems.                                                           
                                                                              
SATELLITES:   Trajectory data during flybys at 20-second resolution.          
              Data divided by the satellite Galileo was passing during        
              the flyby and are provided in "satellite-centric" coordinates.  
              See GO_POS_SC_MOONCRDS_DS.CAT (/CATALOG directory) for details. 
                                                                              
SURVEY:       Trajectory data during orbits at a variable resolution          
              (generally 10-30 minutes) in several Jupiter centered           
              coordinate systems.                                             
              See GO_POS_SC_JUPCRDS_DS.CAT (/CATALOG directory) for details.

GO-J-POS-6-MOON-TRAJ-JUP-CRDS-V1.0  contains the locations of the Galilean    
    satellite and the Galileo in System III (1965.0) coordinates, plus        
    the Sun and Earth phase angles of all bodies when Galileo was inside      
    of 30 Rj. See GO_POS_MOONS_JUPCRDS_DS.CAT (/CATALOG) for details.         
                                                                              
GO-J-POS-6-ROTORATTITUDE-V1.1 contains the Galileo rotor (spinning part of    
    the spacecraft) attitude (RA, DEC, TWIST) as a function of time. See      
    GO_ATT_DS.CAT (/CATALOG) for details.
