In an application I have to analyse I found this trajectory description for the space probe cassini, unfortunately header and comments have been removed:
2004 6 01 00.0 16669287.46 -13098482.32 -10225933.05 1313468.24
The file format is .trj / .traj. Supposedly, there was a tool called SKYMAP which created these? I would like to know which tool created this data set. From the source code I gather that the table is in the format
year month day hour ignore x y z
The column ignore is ..ignored. I tried to recreate the output with JPL's horizons system but it does not quite fit.
edit: When we develop the application further I want it to be ready for future space missions. I might replace the trajectory description completely. I know asking for opinions is frowned upon, but what would you choose: spice toolkit or horizons toolkit? The spice toolkit seems more extensive and well-kept.
