Package org.orekit.files.ccsds.ndm.adm.apm

Class Maneuver

  • All Implemented Interfaces:
    Section
    public class Maneuver
extends CommentsContainer
    Maneuver in an APM file.

    Beware that the Orekit getters and setters all rely on SI units. The parsers and writers take care of converting these SI units into CCSDS mandatory units. The Unit class provides useful fromSi and toSI methods in case the callers already use CCSDS units instead of the API SI units. The general-purpose Unit class (without an 's') and the CCSDS-specific Units class (with an 's') also provide some predefined units. These predefined units and the fromSi and toSI conversion methods are indeed what the parsers and writers use for the conversions.

        public void validate​(double version)
        Check is all mandatory entries have been initialized.

        This method should throw an exception if some mandatory entries are missing or not compatible with version number.

        Specified by:
        validate in interface Section
        Overrides:
        validate in class CommentsContainer
        Parameters:
        version - format version

        public AbsoluteDate getEpochStart()
        Get epoch start.
        Returns:
        epoch start

      • setEpochStart

        public void setEpochStart​(AbsoluteDate epochStart)
        Set epoch start.
        Parameters:
        epochStart - epoch start
