Class Oem

java.lang.Object

org.orekit.files.ccsds.ndm.NdmConstituent<OdmHeader,OemSegment>

org.orekit.files.ccsds.ndm.odm.oem.Oem

All Implemented Interfaces:

EphemerisFile<TimeStampedPVCoordinates,OemSegment>

public class Oem
extends NdmConstituent<OdmHeader,OemSegment>
implements EphemerisFile<TimeStampedPVCoordinates,OemSegment>

This class stores all the information of the OEM File parsed by OEMParser.

It contains the header and a list of Ephemerides Blocks each containing metadata, a list of ephemerides data lines and optional covariance matrices (and their metadata).
