Main differences between V11.6.2 and V11.7.1

This new version does not include too many evolutions but profits of evolutions and corrections coming from the GENIUS and GENOPUS new versions.

Dependencies

This version uses GENIUS V1.12.1, GENOPUS V2.4.1, PATRIUS V4.10.2 and PATRIUS_DATASET V1.4.3. Mainly due to the change of the versions of the two last ones, some numerical differences may occur.

Initial orbit input improvements

Thanks to the new GENOPUS version, the way to enter the initial orbit has been improved : the main evolution is the fact that it is now possible to enter mean elements. Nevertheless, PSIMU will still propagate its trajectories with a numerical integrator using osculating parameter.

For more details on the orbit widget, see here.

Automatic results save

New checkboxes are now present in the Output Tab, defining how it is possible to save automatically some or all the results files. These files will be named with the epoch of the operation (for example EPH_result_2023-03-31T13-46-34.txt).

New arguments for the batch mode

Thanks to automatic save (see above), there is now the possibility to define which files will be saved via the context file. Anyway, it is allways possible to use the "-o" option in batch mode (see here). This "-o" will only give the suffix name but the files that will be really saved will be :

  • SQLite file
  • EPHEM and EVENT files if -e or --ephem argument is present
  • VTS files if --vts argument is present (as in the previous versions)
  • Final orbit XML file if --orbit argument is present

WARNING : due to this modification the by default name of the output SQLite file is no more psimuOutputData.db but PSIMU_result.db using GUI and PSIMU.db else.

VTS Events files

In the previous versions, the VTS events files included only the epoch and the name of each events. Now, it is also possible to get additional colums as the ones defined for the EPHEM or EVENT files.

Anomaly corrections

  • More robust error management for mean parameters as output variables.
  • Add of the ".txt" suffix when using the "-o" argument in batch mode.
