CDAWEB provide 'ssc' for users to get the position and the footpoint position of THEMIS, for example the 'L_VALUE' 'NorthBtrace_GEO_LON' variable in cdf and so on.

If the user wants to only obtain satellite position data, or wants to reduce the calculation and time overhead caused by trace field lines, it is necessary to add a data interface to 'ssc'.
