After each run when using GUI or, for the batch mode, using the "-o" option or, for the Java API using specific methods, both xlsx and csv files will be created with a lot of interesting information.

The content of a csv file is the same as for the xlsx file. The advantage of a csv format is the fact that it is sometimes easier to use. The xlsx format allows to see in a more ergonomic way (cells formats) the results.

Anyway, the content of such files is for any object studied:

  • Norad Id
  • Name
  • Country
  • Perigee altitude of the last TLE (km)
  • Apogee altitude of the last TLE (km)
  • Inclination of the last TLE (deg)
  • Computation date (calendar format) : corresponds to the End of history date
  • Shortest reentry date (calendar format)
  • Reentry date (calendar format)
  • Longest reentry date (calendar format)
  • Reentry date error (days)
  • Drag a priori S/m (m2/kg)
  • Drag refined S/m (m2/kg)
  • Drag S/m after orbit determination (m2/kg)
  • SRP Refined S/m (m2/kg)
  • Amount of semi-major axis maneuvers
  • Date(s) of the semi-major axis maneuvers
  • Amount of inclination maneuvers
  • Date(s) of inclination maneuvers
  • Comments about the calculation : OK or error message


An xlsx file looks like this …
