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, outputrun, results, work, tles, tlesbyday) will be created if it does not already exist. These directories will be used to store data/results working files. Note that the name of these directories may be changed (see specific page on properties 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:
- in the tles/ subdirectory with the following organization: XXX/YY/XXXYY.tle file where XXX are the first three digits of the NoradId; YY are the last two digits of NoradId. the .tle contains history of TLE for this NoradId
- in the tlesbyday/ subdirectory with the following organization: YEAR/DAY.2l file which contains for a specific day, the last TLE for each object that has been updated during the last year and that is still in orbit.
