Method Detail

getOrbitalCovariance

OrbitalCovariance getOrbitalCovariance(AbsoluteDate date)
                                throws PatriusException

Getter for the OrbitalCovariance at the provided date.

Parameters:

date - The date at which the orbital covariance is wanted

Returns:

the orbital covariance at the provided date

Throws:

PatriusException - if orbital covariance cannot be computed at the given date

getPVCoordinates

default PVCoordinates getPVCoordinates(AbsoluteDate date,
                                       Frame frame)
                                throws PatriusException

Get the PVCoordinates of the body in the selected frame.

Specified by:

getPVCoordinates in interface PVCoordinatesProvider

Parameters:

date - current date

frame - the frame where to define the position

Returns:

position/velocity of the body (m and m/s)

Throws:

PatriusException - if position cannot be computed in given frame
