User Manual

PSIMU may be used very quickly via its GUI facilitating context elaboration and results exploitation. No code knowledge is necessary. It is also possible to use it in batch mode via a shell and especially on grid computers with no display properties. On the other hand, it is also possible to use it via its Java interface inside a higher level tool (for example, an orbit determination tool or a maneuver optimization tool).

So, three jar files are available:

• psimu-NN.n-jar-with-dependencies.jar : executable jar including all needed libraries => it is the file to use for GUI utilization but it may also be used for the Java interface
• psimu-NN.n.jar : includes only PSIMU classes => to be used for Java interface, under the condition of linking with the right version of [GENOPUS] and [PATRIUS]
• psimu-NN.n-javadoc.jar

The GUI mode

• Overall presentation: main explanations on the product philosophy
• Initial Orbit: initial orbital parameters
• Earth features: Earth shapes and frames conversions definition
• Vehicle: vehicle caharacteristics
• Forces: force models to be used
• Maneuvers: maeuvers sequence
• Attitude: attitude sequence
• Integrator: propagation data , specially numerical integrator tuning
• Events: list of orbital events
• Output: outputs selection
• Console: synthetic results display
