Quick start

OPERA proposes a lot of options and configurations. Anyway, in order to allow to start first computations very quickly, the OPERA GUI, many parameters are set to default values.

Launch the main GUI

To launch the GUI you only have to double click on Windows systems or type :

 java -jar opera-xx.x-jar-with-dependencies.jar

The first time, the GUI is launched a specific directory ('OPERA_DATA) as sub-directories (context, results, work, ') will be created if it does not already exist. These directories will be used to store data/results working files.

Mandatory data

If many data are included in the jar file (solar activity, force models data, ...), no TLE data are directly provided. So the user will have to get it for example via the [Space-Track site]. By default, these TLE will be stored
