generateKeplerianOrbit

public KeplerianOrbit generateKeplerianOrbit()
                                      throws OrekitException

Generate a KeplerianOrbit based on the OMM mean Keplerian elements. If the reference frame is not pseudo-inertial, an exception is raised.

Returns:

the KeplerianOrbit generated from the OMM information

Throws:

OrekitException - if the reference frame is not pseudo-inertial or if the central body gravitational coefficient cannot be retrieved from the OMM

generateCartesianOrbit

public CartesianOrbit generateCartesianOrbit()
                                      throws OrekitException

Generate a CartesianOrbit from the KeplerianOrbit.

Returns:

the CartesianOrbit generated from the OPM information

Throws:

OrekitException - if the Keplerian Orbit cannot be generated

generateSpacecraftState

public SpacecraftState generateSpacecraftState()
                                        throws OrekitException

Generate spacecraft state from the KeplerianOrbit generated by generateKeplerianOrbit. Raises an exception if OMM doesn't contain spacecraft mass information.

Returns:

the spacecraft state of the OMM

Throws:

OrekitException - if there is no spacecraft mass associated with the OMM

generateTLE

public TLE generateTLE()

Generate TLE from OMM file. Launch Year, Launch Day and Launch Piece are not present in the OMM file, they have to be set manually by the user with the AdditionalData static class.

Returns:

the tle
