Printing : Différence entre versions

Version du 11 juillet 2017 à 10:44

Once the propogation done, it is possible to use some utilities methods to print results or strore them in some files.

Printing results

First, we can use the printSV() method as in this example :

    test.printSV("BEGIN", iniOrbit, FramesFactory.getEME2000(), mm);
    final SpacecraftState sc = test.propagateInSlaveMode();
    test.printSV("END", sc.getOrbit(), FramesFactory.getEME2000(), mm);

This will display something like that ...

Storing results

Another solution is to store results in files when PSIMU is in master mode:

    final Psimu psimu = new Psimu(iniOrbit, EARTH, integrationData, assembly, mm, forces, manSeq, seqAtt);
 
    final OutputConfig output = new OutputConfig(FramesFactory.getEME2000(), LOFType.LVLH, 86400.);        
    psimu.propagateInMasterMode(output, null);
 
    psimu.saveResults(output, "test", true);

This will create [VTS] files (VTS_EPH_test.txt, VTS_EVE_test.txt and VTS_ATT_test.txt) as well as a binary file named (resultsPropagation.ser). From V11.1, this file will be [SQLite] format and thus, could be used by many utility tools taking into account this format.
