Printing

Printing

Once the propogation done, it is possible to use some utilities methods to print results or store 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 ...

BEGIN Frame EME2000 Mass (kg) 1000.0 T (h) 1.4917487906426035 A (km) 6628.137000000006 Ex 8.881784197001211E-16 Ey -8.542591124194022E-23 Inc (deg) 51.59999810577826 Raan (deg) 7.714051151482253E-6 X (km) 6628.136999999962 Y (km) 4.69158061035269E-4 Z (km) -5.339771250296284E-4 Vx (km/s) 1.4865627172522409E-7 Vy (km/s) 4.816905268016365 Vz (km/s) 6.077421519614858 END Date (TAI) 2010-01-01T13:48:07.345 Frame EME2000 Mass (kg) 1000.0 T (h) 1.3468381128010898 A (km) 6191.624504771174 Ex -0.06671952301093685 Ey -0.0300290461308641 Inc (deg) 51.59999810577824 Raan (deg) 7.714051168045088E-6 X (km) 2163.0125242789236 Y (km) 3798.414653291644 Z (km) 4792.405891341955 Vx (km/s) -7.343036365577201 Vy (km/s) 1.3329935495415233 Vz (km/s) 1.6818204305631719

Storing results

Another solution is to store results in ASCII VTS 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.saveVTSFiles("OUTPUT_JPSIMU", "test");

The last line of code will create VTS files (VTS_EPH_test.txt, VTS_EVE_test.txt and VTS_ATT_test.txt).
