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.

Launch the main GUI

To launch this 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 an 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 ...
