| | + | Welcome to the <font color=#556B2F>'''PSIMU'''</font> wiki, a [https://cnes.fr/fr '''CNES'''] flight dynamics tool. As it is coded in <font color=#FF8C00>Java</font>, this product is available for any kind of platforms owning a <font color=#FF8C00 title="JavaVirtual Machine">JVM</font>. |
| | | | |
| | + | == DESCRIPTION == |
| | | | |
| − | <font color=#FF0000>'''!!! BE CAREFUL, THIS WIKI IS UNDER UPDATE FOR THE PSIMU V11.1 version !!!'''</font>

| | + | ::<font color=#556B2F>'''PSIMU'''</font> is a [https://cnes.fr/fr '''CNES'''] tool allowing to propagate trajectories around the Earth. |

| | | | |
| − | <font color=#556B2F>'''PSIMU'''</font> is a [https://cnes.fr/fr '''CNES'''] tool allowing to propagate trajectories around the Earth. These trajectories may be:
| + | ::The current version is: <font color=#FF0000>'''V11.7.4'''</font>. |
| − | * <font color=#FF0000>'''Elliptical'''</font> ones (all kind of orbits, from <font color=#FF8C00 title="Low Earth Orbit">LEO</font> to <font color=#FF8C00 title="Geostationary Earth Orbit">GEO</font> passing through <font color=#FF8C00 title="Medium Earth Orbit">MEO</font> or <font color=#FF8C00 title="High Elliptical Earth Orbit">HEO</font>),
| + | |
| − | * <font color=#FF0000>'''Hyperbolic'''</font> ones,
| + | |
| − | * <font color=#FF0000>'''Atmospheric'''</font> ones (in particular in case of debris reentries).
| + | |
| | | | |
| − | <font color=#556B2F>'''PSIMU'''</font> is usable via three modes:
| + | [[Previous_versions|'''Previous versions''']] |
| − | * <font color=#FF8C00 title="Graphical User Interface">GUI</font>: its utilization is made user-friendly thanks to a graphical user interface (developed using [[https://logiciels.cnes.fr/fr/node/76?type=desc GENIUS]] and [[https://logiciels.cnes.fr/en/node/78?type=desc GENOPUS]]),
| + | |
| − | * Batch using a context file (in <font color=#FF8C00 title="Extensible Markup Language">XML</font> format),
| + | |
| − | * Library via its <font color=#FF8C00>Java</font> interface.
| + | |
| | | | |
| − | Its initialization is made by:
| + | ::Describes evolutions thanks to previous versions. |
| − | * The initial orbital parameters definition (epoch, frame, coordinates) with a great number of available options.
| + | |
| − | * The vehicle modelling:
| + | |
| − | :- Vehicle shapes (sphere, cylinder and parallelepiped) with or without solar panels,
| + | |
| − | :- Dimensions or surfaces,
| + | |
| − | :- Aerodynamic characteristics and/or radiative pressure ones,
| + | |
| − | :- Propulsive characteristics (engines, tanks).
| + | |
| − | * A maneuver sequence (optional) including impulsive maneuvers and/or continuous ones
| + | |
| − | * A sequence of attitude laws (optional) ; indeed, if PSIMU does not manage 6 DDL motion, it owns as input data, attitude laws depending on orbital events, allowing to know at every moment the vehicle attitude and thus, to deduce from it the forces applied to the vehicle.
| + | |
| − | * Numerical integrator parametrization (<font color=#FF8C00>Runge Kutta</font> or <font color=#FF8C00>Dormand Price</font>) with, for usual applications, by default settings.
| + | |
| − | * Choice of force models within:
| + | |
| − | :- Potential with several models available as the possibility to manage degree and order of zonal and tesseral terms,
| + | |
| − | :- Other bodies attraction : Moon and Sun via analytical or numerical ephemeris,
| + | |
| − | :- Atmospheric forces using different atmospheric models and their associated settings,
| + | |
| − | :- Solar radiative pressure (direct or rediffused one)
| + | |
| − | :- Oceanic and terrestrial tides
| + | |
| | | | |
| − | <font color=#556B2F>'''PSIMU'''</font> also allows to set its output data within several tens of variables, the output frame and, of course, the output step. A graphical interface for plots is also integrated.
| + | == USE IT == |
| | | | |
| − | == How to use it? ==
| + | [[Where_to_get_it|'''Where to get it?''']] |
| | | | |
| − | <font color=#556B2F>'''PSIMU'''</font> may be used very quickly via its <font color=#FF8C00 title="Graphical User Interface">GUI</font> facilitating context elaboration and results exploitation. No code knowledge is necessary.
| + | ::Where to download it. |
| − | 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 <font color=#FF8C00>Java</font> interface inside a higher level tool (for example, an orbit determination tool or a maneuver optimization tool).
| + | |
| | | | |
| − | So, three jar files are available:
| + | [[Quick start|'''Quick start''']] |
| | | | |
| − | * '''psimu-NN.n-jar-with-dependencies.jar''' : executable jar including all needed libraries => it is the file to use for <font color=#FF8C00 title="Graphical User Interface">GUI</font> utilization but it may also be used for the <font color=#FF8C00>Java</font> interface
| + | ::First steps with <font color=#556B2F>'''PSIMU'''</font> |
| − | * '''psimu-NN.n.jar''' : includes only <font color=#556B2F>'''PSIMU'''</font> classes => to be used for <font color=#FF8C00>Java</font> interface, under the condition of linking with the right version of GENOPUS and PATRIUS)
| + | |
| − | * '''psimu-NN.n-javadoc.jar'''
