Class OEMFile

java.lang.Object

org.orekit.files.ccsds.ODMFile

org.orekit.files.ccsds.OEMFile

All Implemented Interfaces:

OrbitFile

public class OEMFile
extends ODMFile

This class stocks 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).
