generateKeplerianOrbit

public KeplerianOrbit generateKeplerianOrbit()

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

generateCartesianOrbit

public CartesianOrbit generateCartesianOrbit()

Generate a CartesianOrbit from the KeplerianOrbit.

Returns:

the CartesianOrbit generated from the OPM information

generateSpacecraftState

public SpacecraftState generateSpacecraftState()

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

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
