Quick start
PSIMU proposes a lot of options and configurations to propagate an orbit. Anyway, in order to allow to start first simulations very quickly, the PSIMU GUI, many parameters are set to default values.
Sommaire
Launch the main GUI
To launch the GUI you only have to double click on Windows systems or type :
java -jar psimu-xx.x-jar-with-dependencies.jar
The first time, the GUI is launched a specific directory (where result files will be stored) will be created : OUTPUT_JPSIMU
Initialize mandatory data
Then, it has been decided to avoid to get too many default values. Only the following parameters must be initialized:
- orbital parameters which will be set to zero
- attitude law
Initial orbit
Enter a non nul semi mlajor axis (for example 7000 km) in the orbit tab:
Attitude law
Select the default law as the single attitude law.
Dry mass
It is possible to let the initla dry mass to zero as below. Nevertheless, if the user will add some forces, attitudes or anything that needs to divide by the total mass, then, an error message will be sent and the propagation will not be launched.
Propagate
At the end, we have just to start the propagation by clicking on the Start button ...
