Package org.orekit.files.ccsds

Class OGMFile

  • Direct Known Subclasses:
    OMMFile, OPMFile
    public abstract class OGMFile
extends ODMFile
    This class gathers the general state data present in both OPM and OMM files.

    This class does not appear in the CCSDS standard, it is only a design feature of Orekit to reduce code duplication.
